Wojciech Czaja MATH416 Expecting an A Anonymous 12/06/2024	Like the 12/02/24 review says, the prof doesn't really give us example problems of the material when we are first introduced to it. He also does sometimes skip steps in his lectures and makes some things sound obvious when they are not. The title of the class "Applied Harmonic Analysis: An Introduction to Signal Processing," can be somewhat misleading. The exams and lectures are mostly theoretical and the homework include some theory and some application (mainly in the form of MATLAB coding). I'll break down each of these 3 components: Lectures: Pretty theoretical especially towards the middle and end. Expect to know linear algebra pretty well (Math240 material, idt Math405/401 is necessary). Czaja is a good lecturer though in that his lectures are very structured and easy to follow. He posts his notes online and his notes are very detailed (almost too detailed, but like one reviewer said, he sometimes writes certain things are "easy to see" when they aren't). You should still go to class though because he does say things in lecture that aren't in the notes Exams: This is what most people have mixed feelings about. Like previous reviewers mention, if you can see the trick/gimmick on each question, the exams are easy, otherwise the exams can be tough. This, on top of the fact that the prof doesn't go over many examples/doesn't make practice exams, means the only "real" way to study for these exams is to try stuff out on your own and study the lecture notes rigorously. While there are some problems in the profs lecture notes that do help, some exam questions will catch you off guard and there's no real way to expect it. Averages on exams are in the 60-70% range. Homeworks: Mostly chill, some are theoretical but not egregious and others are just implementing stuff in MATLAB. Studying the homeworks can sometimes help for the exams too. Pretty sure most of the class did well on the homeworks Additional Info: His grading is so that your lowest 2 homeworks get dropped and lowest midterm (out of 3) gets dropped. For Fall 2024, he again implemented the policy where you can take the grade of all 3 midterms and the first 8 homeworks as your final grade, and not take the final. However, for Fall 2024 our third midterm was NOT take home (and was also the day we came back from Thanksgiving Break). TLDR: If you care about/enjoy the theoretical math that propels signal processing and data representation techniques, this class might be for you. If you don't mind spending time on your own investigating these theoretical aspects, this class is for you. Else, I can understand why some people are frustrated with the way this class is taught and you might be better off taking something less stressful.
Wojciech Czaja MATH416 Anonymous 12/02/2024	I do not understand why Czaja's review score is so high, he's a decent lecturer but he does his best to make the material as obtuse as possible and give as little actual help as he can, all while feeling kinda pompous about it the whole time. He does not do examples, he does not explain the application of the material that you're teaching you, and he does not give you practice problems. I have our third exam tomorrow, and I have gotten no feedback on any of the three homework assignments I have turned in on this material. There is no POSSIBLE way for me to know if I actually understand the material or not. The textbook has typos and is difficult to comprehend, and often skips huge chunks of work saying that it is "easy to see" how something works out, which is simply lazy writing. A few lectures ago he gave the entire class a quadratic system of equations with four variables, one of the few actual example problems he has done this entire semester, and not one person knew how to do it. Rather than actually do his job and teach us, he made fun of us for not knowing something that "a highschooler should know how to do" and then proceeded to just write the answer on the board without showing how he got it. I went to his class notes to see a deeper derivation only to find even in the notes he says "it's easy to see" and then not explain it. I realize that the class material is difficult, but if he actually explained what we were doing instead of just spouting theory at us for 3 hours a week it might be easier to understand. We're nine lectures in to the unit on wavelet transforms and I still could not tell you what they actually do. This class fundamentally fails to teach you signal processing. Sure I know how the transforms are defined, but if you asked me what the use case was for them I would not have the slightest idea where to start.
Wojciech Czaja MATH416 Expecting an A Anonymous 05/08/2024	Things to note: 3 midterms one of which is dropped; 10 hws 2 of which are dropped In our class, the third midterm was a take-home free one (basically guaranteed 95+) and so, the best of Midterm 1 and Midterm 2 (which are legit midterms) along w/ M3 are going to make the 2 midterms that count for your grade. He will offer an opportunity to drop the final and take the score of the 3 midterms and the first 8 hws if you want to take that opportunity up. Regarding the homeworks, most of them are pretty chill -- he doesn't really offer help in OH though so you gotta learn through Stack Overflow, GPT, and just trying stuff out. The midterms are challenging asf -- the thing is they aren't really anything like the homeworks and are way more proof-based than what you'd expect given what he describes the midterms as. Only 1 or 2 of the questions are "here, do it" questions, the rest are showing some type of property or proof question which is significantly harder. As others mentioned, if you can notice the gimmick fast enough, it's normally a 2-3 liner. If you can push yourself through, it can take 10-15 minutes sometimes and you can get the answer. But chances are, you might just f*ck it up because there's no really good way to prepare (you just have to remember and notice the right things in the moment). Definitely use the practice problems from his notes though because they are somewhat similar to the actual midterm (the homework problems that he assigns aren't though). Lecture-wise, he's pretty good. Just, it gets a bit tiring after a while especially because a lot of the content is cumulative (especially near the end of the course), so if you forget things from previous lectures, you're kinda F-ed. That being said, the accent isn't really an issue and you get kinda used to the whole structure of the course after a while. All in all, I'd just suggest being TOTALLY aware that you're interested in DSP stuff before taking this course becuase while the material can be extremely interesting and fun to learn, if you're not interested enough for it to motivate getting through the times where you're misunderstanding things or have to read through the notes, you'll ultimately end up hating the course and neglecting it leading to not great outcomes. Overall, pretty good course, but requires more mathematical maturity than just a MATH240+MATH141 prereq (I think he should also add a MATH401 or MATH405 pre-req as well since some of the linalg does get a bit crazy). Make sure to attend lecture and focus/lock-in on the shit so you don't fall behind.
Wojciech Czaja MATH416 Expecting an A+ Anonymous 02/20/2024	416 content is definitely challenging but Czaja explains it very well. Content is genuinely interesting. He writes exams so that all questions have 2-3 line simple (elegant) answers, especially proofs, but if you don't catch it at the moment exams are hard. Cheat sheet is allowed and he drops one midterm. Getting a good grade in this class isn't hard if you keep up with homework and average 70s on exams. He changed the final to be optional for our class.
Wojciech Czaja MATH631 Anonymous 03/19/2022	my god, comparing to last semester's 630, he's an angel managing this class. Structure-wise this course is 630 take away all the stressful in class exams. Couldn't ask for more.
Wojciech Czaja MATH630 Anonymous 12/30/2021	He has high expectation for the class. I didn't like him at first as he came off as serious and intimidating. But as the course progressed I started to appreciate his philosophy and found him a rather charming professor. Also gave us candies for halloween. Homework was consisted of problems from the text. Exams were short and quick as long as one is familiar with all the results and counterexamples. There were many questions of the nature "does X theorem still hold if we drop the Y assumption", so make sure you know all the theorem statements by heart. Preparation for the final stressed me out - he made it clear that he'd assess our understanding of the big picture of all the convergence modes and function spaces. Miraculously the university switched covid policy and made our final optional just before the exam could take place. Czaja gave us a good deal regarding grades and I suspect few in the class actually took the final.
Wojciech Czaja MATH630 Expecting an A- Anonymous 12/29/2021	Not sure if this helps since only one professor is teaching this class for the year, and there is no choice. He's knowledgeable and smart. He talks about the history of mathematics during lectures, which I consider rather rare. He's also helpful during office hours. The textbook is available to university students via the online library or the course elms site. He covers everything until the Radon-Nikodym theorem and L-p spaces. He usually covers L-p spaces but not the R-N theorem in the first semester. The course content is exactly the topics on the textbook not including some fringe materials on the book. His homework is hard but doable, just costs a huge amount of time. His exams are hard but the grading is lenient. Harder exam questions are similar to easier homework questions. He asks for counterexamples a lot, so better if you have a bank of counterexamples prepared so you don't need to come up with one during the exam. If the question is about proving or giving a counterexample to a statement, then a correct T/F gets 2/20, a counterexample gets 10/20, and with justification, you get 20/20. The proof questions are easier and I didn't get points off so no idea how he grades them. Sometimes hand-wavy justifications also get the points as long as the example is right, unless the justification is completely off.
Wojciech Czaja MATH416 Expecting an A+ Anonymous 12/10/2019	For this class, he's honestly a really good lecturer. He explains how things came to be and why things matter, which is always a good thing when introducing left field concepts. So I enjoyed his lectures a lot. Overall the class is pretty straightforward in the content, as his lecture notes span maybe 30 or 40 pages for the entire course (of course, they are not fully complete). He also allows for students to make up grades with an extra-credit project worth around 10%, but the project comes with very high standards. The exams are what I call "troll": as a veteran student of mathematics they consist of various little tricks which are decently easy to see if you are decently mathematically mature and which seem intractable if you are not, which is why the exam averages are 60-70%. Overall the course is interesting and I would recommend people take it for an elective or something like that.
Wojciech Czaja MATH141 Expecting a C- oopboop 06/20/2016	Czaja's grading was extreme and the opposite of lenient. No partial credit was given. The final exam was easy, but the other exams were the hardest exams I've ever taken. Class average was a D+. Czaja was a great lecturer but his exams were too hard compared to lecture. I wouldn't suggest taking him at all.
Wojciech Czaja MATH141 Expecting a B Anonymous 12/02/2015	Ok this guy's lecture is quite real. He explains stuffs at such a complicated and minor level that I have no clue as to what is happening. Furthermore, his examples in class are so basic. I learned more for discussions than I did from lectures. His accent is quite distracting also. The quizes are hella easy, but I feel he types "hardest calc problems ever made" in google to get the four problems he needs for the exams. In the final exam he will probably make us prove fermat's last theorem, so can't wait for that. My grades went like 72 100 52 (fourth one will probably 43 or something). This guys is chill doh, and he is wayyyy more lenient than the other lecturers. So pick this guys. oh and he is funny af.
Wojciech Czaja MATH141 Expecting an A nassu30 02/18/2015	A wonderful teacher. Accent can a bit difficult to follow though. But makes the subject matter easy. His way of grading was far by one of the best. 4 exams-lowest dropped 7 quizes- lowest 2 dropped A flat score of 50 for scoring atleast 30% on Web Assign and no weekly deadline for homework. I got an A in his class. Definitely take him
Wojciech Czaja MATH411 Expecting an A zhangsta 05/30/2014	Dr. Czaja is great professor. He makes a lot of jokes in class and is willing to answer questions in class, but don't expect much help on homework problems in his office hours. The homework problems were assigned out of the book. The exams he wrote were pretty difficult, but then again, so was the material. Some of the questions were problems from the homework, but asked in a way to make you think about the problem in another way.
Wojciech Czaja MATH141 Expecting an A testudo_ourumd 12/19/2013	Dr. Czaja (pronounced cha-ya for others who may not be fluent in polish) was quite a character. He first came off as a little mundane but as the semester progressed, he would tell more and more jokes in his matter of fact tone which made them even funnier. For my semester (FA13) he gave 4 exams and 7 quizzes. Each exam was 100 points, and 1 was dropped. Each quiz, administered by your TA, was 20 points, and 2 were dropped. Homework was through WebAssign, which Czaja states very clearly is terrible. He is sort of forced by departmental people to use it, apparently, so of our homework grade, if we complete 30% of homework in general for the semester, you get the 50 points for homework. My only complaints would be that he is sometimes a little slow with putting out the practice problems for the exams/quizzes. For example, he didn't send the answers to the practice final exam until 4 hours before the exam was held...sort of annoying. Speaking of the final, it is a test made by the Calc II department head and is considerably tougher than Czaja's exams, at least this year. I got a 99, 100, 99, and 87 respectively on Czaja's four midterms, while hardly getting an 84.5 on the final. Be prepared to study your butt off for the final and DO PREVIOUS EXAMS. Czaja said that "practicing the previous exams will only tell you what will NOT be on this one" and while that is partially true, the topics are more or less exactly the same and the questions are asked in the same way since the same guy writes it every year (thus far). Work hard, and you can get a great grade. I worked hard and got the highest grade in my 200 person lecture (617/650 total possible points).
Wojciech Czaja MATH141 Expecting a B Anonymous 12/26/2011	Dr. Czaja's grading scale was: 90-100 = A 75-89 = B 60-74 = C 50-59 = D The total class was out of 650 points made up of 4 100 point midterms(1 dropped), 19 10 point quizzes(4 dropped) and the final 200 point exam. Dr. Czaja does webassign but does not include it in the grade. Dr. Czaja, unlike many of his colleagues(Or maybe they just don't care, which is very possible) recognizes how poorly the webassign system is designed and the high frequency of lost points where a student puts in 'c' for the constant rather than 'C', among other issues. In studying for the midterms, focus on the review problems Dr. Czaja posts on his website rather than webassign, because those are more likely to be on the exam. Only after doing all the practice problems should you bother with webassign. This is the MATH department, so your success all depends on who the TAs for your lecture are and the TA you have for your discussion. And for the departmental final, the TAs for the course that semester. I lucked out with a very good TA for my discussion, Adam, who explained topics well despite the early hour of the morning, wrote helpful explanations on our quizzes as to where we went wrong, was easily approachable after discussion and in office hours. Furthermore, he took the time to write us up review packets for a few of the midterms. On the other hand, there was also a TA that was very strict on their grading, and according to some of my classmates(unconfirmed second hand), a much less valuable TA in discussion. Dr. Czaja's lecturing style is essentially basic proofs. He'll go over basic examples for each of the required concepts, and leave more difficult examples for TAs to go over in discussions. While Dr. Czaja has a fairly strong accent, it's very easy to understand, and his chalkboard handwriting is clear enough to understand as well. The textbook, the same book from Calculus 1, is useless. It is used in Calculus 2 to 'save Calculus I students money' as they continue in their Calculus track. There are better free textbooks and resourcecs online, such as <http://tutorial.math.lamar.edu/> The person with the authority to assign the textbook for Calculus 1 is none other than Dr. Denny Gulick, who is the author of the textbook, and profits from every copy sold. The Mathematics department as a whole cares very little for undergraduate students, and contradictory to the goal of education, spends your tuition dollars doing its very best to minimize the # of people who succeed in their classes, which are required for every student in CMNS and ENGR. Despite all this, Dr. Czaja cares about his students' success, even in undergraduate. If you can, take his lecture of 141.
Wojciech Czaja MATH141 Expecting a C Hosea 12/21/2011	Calculus 2 is HARD. However, Czaja has a very forgiving grading system which makes it easier for one to get a high grade. 50% is a D, 60% is a C, 75% is a B, 90% is an A. There are 4 exams during the semester (drops 1) and 19 quizzes (drops 4). I will admit I have a very weak math background, taking precalc and calc 1 from a community college and coming here to take Calc 2. Most people I know that came to UMD after community college and took calc 2 had to retake calc 1 again. But I managed to squeak by after thinking I was going to get a D in this class. Dr. Czaja's a really nice guy, and seems to be clear when he lectures in class. I noticed that a lot of people don't seem to show up though. I think it is because he usually does examples from straight from the book. This Fall 2011 semester, Czaja did not require webassigns for hw, so that was a big plus. However, it can be a double-edged sword because you end up not getting necessary practice for the concepts if you aren't diligent enough. So I suggest you just do the problems in the book instead. Once again, I stress that this class is hard. You have to do hw daily and make sure you actually understand the concepts as they come or you'll end up with a C like me, which could have been very avoidable, especially with Czaja's grading system. The good thing though, is that its almost impossible to get lower than a C in this class. I got a 65, 50, 64, 66 respectively on the exams and a low quiz average and somehow managed to get a C. If you get anything lower it's because you blew off this class.
Wojciech Czaja MATH141 thisismygrade 08/07/2011	Does professor Czaja give practice exams for 141 and how many exams are there? Thank you
Wojciech Czaja MATH141 Anonymous 07/29/2011	Prof Czaja is an okay prof. His exams and quizzes are fairly easy, but I hated his teaching style. He spent half the class wiping the board. Assignments (when I took him in Fall2010): 3 exams (drops lowest), 27 hw's (drops 7), 7 quizzes (drops 2), and the final. His grading scale is on a curve (a 75 is a B and an a 60 is a C).
Wojciech Czaja MATH141 Expecting an A RLJ2009 01/18/2011	I heard horror stories that Cal 2 is the worst of all three of the Cals, but with Czaja is was very easy to get an A as long as you studied hard. For half the semester he was a good teacher, then when it got to chapter nine he just stopped being helpful and I had to rely heavily on Math Success Program. He drops a test, two quizzes, and five homeworks. Also his curves are so kind. I got a B in Cal and managed to get an A in Cal 2. Would definitely take if you don't mind teaching yourself and reaching out to outside help!
Wojciech Czaja MATH141 Expecting a B Anonymous 01/16/2011	Czaja was a very good teacher however, the final exam had problems more difficult than exams or quiz's. Czaja made us laugh just about every class. Homework was assigned on the website webassign. These problems were a real pain. The first problem on every exam was graded for either full credit or no credit. Czaja actually awarded everyone twenty points when almost everyone one of these wrong.
Wojciech Czaja MATH141 Expecting a B F00zball 12/16/2010	Czaja is a great teacher. He absolutely knows his shit. I can't remember a single instance of him not knowing how to do a problem or stumbling when answering a question. He comes in and starts class right away. He's got an accent but it's nothing bad, you can still understand everything he is saying. Class is generally engaging and he is hilarious when he jokes around. Some of the material is hard imo, and you will probably need to go to class and look at the textbook after. He drops a ton of the grades, curves when necessary, and his tests are pretty fair. The final was ridiculous though. I thought I was going to get a C but ended up with a B. Recommended.
Wojciech Czaja MATH141 recjra 12/16/2010	Prof. Czaja was easily the best math professor I have had. He was able to explain the concepts very concisely and I felt like I actually learned in his class instead of simply memorizing what we needed to know for the exams. His grading scheme is awesome and it's basically impossible to fail. Plus, he was a really nice guy and wanted his students to do well.
Wojciech Czaja MATH141 Expecting a B Anonymous 12/07/2010	He has an accent, but its not that big a deal. The biggest problem is that the examples that he uses in class are either way to simple so that you can't really study or learn from them, because the tests are much more complicated, or they are so complicated that it is impossible to understand the material. Additionally his tests are hard, yes he posts old tests to review, but usually there were not solutions posted, and he usually put s them up really, really, late the night before the test so you can't even ask your TA any additional questions about the material on the test. I took AP Calc BC in high school and not only got a 5 and I also got an A in the class. I retook Calc II so that I could refresh and get a solid A as a freshman, and no thanks to Czaja that will not happen despite working my tail off in this class.
Wojciech Czaja MATH464 Expecting a B Anonymous 12/02/2010	Czaja did a very good job of explaining the conceptual basis of Fourier, wavelet, and wavelet packet transforms. He also did a good job of keeping the target of any proof present in the students' minds, but sometimes proofs were a little hard to follow anyway, and some proofs left me with a feeling of "so what" afterward (that is, some proofs seemed to add nothing substantial to my understanding of the nature of the proven proposition - I would've been content with accepting a statement as true and perhaps seeing some cases of it being true or a brief explanation of the gist of the proof). It was also a little hard for me to discern what the instructor expected us to be learning at any given moment. It seemed the exams often were not clearly connected to lecture material (usually there was relevant class material that one could use to solve exam problems, but problems were often presented with notation that hadn't been used in class, such as the use of "inverse Fourier transform" instead of "synthesis formula", so some extra cognitive overhead had to be taken into account). Also, as a student who had no prior experience with Matlab, homework assignments to be complete in Matlab seemed a bit open-ended (though I scored highly on all the ones I've received back), and most of my challenge with the homework came not from my lack of understanding of the mathematical nature of any given transform but rather from particular difficulties of implementing them in Matlab (converting infinite sums over finitely supported sequences into finite sums, making sure that indices of sequences always started at 1 so that calls of values from a sequence would work, etc.). Overall, I learned a lot, and I thought a lot about transforms, but I also spent a lot of time thinking about things that seemed to have little to do with transforms.
Wojciech Czaja MATH141 Expecting a B Anonymous 11/27/2010	This guy was a great professor up until the first test. After that, everything goes downhill FAST. The examples he offers in class are completely useless and unhelpful for studying. Overall I really didn't enjoy taking this class and thought that czaja was very unclear in how he presents the tough material, ex: taylor series, lagrange remainder.
Wojciech Czaja MATH141 Expecting a B Kevin Garcia 11/23/2010	Fantastic professor. Great sense of humor. Posts practice exams the night before the actual exam that are near exact copies of the actual exam. If you can ace the practice exam, you'll ace the actual exam. Has an accent, but rarely gets in the way.
Wojciech Czaja MATH141 Expecting an A- jcywong 07/09/2010	Prof. Czaja is a great Math Professor - if you see him in a course you are thinking about - choose his! He explains Calc quite clearly and definitely enhanced my understanding of the subject. The course IS challenging guys no doubt but if you go to every class and pay attention, do the work there should be no problem. He welcomes questions in office hours and always makes extensions prior to exams. His grading system is extremely fair - a mini-freshmen forgiveness program! Best of all is that his accent and humor, really makes Calc fun especially in that dim smelly armory. I am SO going to miss his famous "well"haha. Wish he taught Calc 3 I would so take his section.
Wojciech Czaja MATH141 Expecting a B+ BIOE 04/08/2010	I don't understand why other people gave really good reviews for him! He does NOT explain things clearly and many people didn't bother to go to class....the only good thing is his grading system is fair! If there is a professor who actually teaches math well like margetis or justin and they are teaching this class TAKE IT WITH THEM! anyways I didn't like him take justin you will be better off!
Wojciech Czaja MATH141 Expecting an A mreese 12/17/2009	Czaja is a very fair and respectful teacher. I really enjoyed his sense of humor and did not find his accent annoying or difficult to understand whatsoever. The practice problems he posts on his website are very helpful and he loves helping students outside of class. Although the tests can be difficult, Czaja's grading system is extremely forgiving, although the no-partial-credit question on each exam can suck if you make a careless mistake. I forgot to write pi in my answer to this question on the first exam, but he generously awarded full credit with a little note reminding me not to do it again. Czaja takes time to explain the interrelatedness between all the concepts, so stuff actually makes sense if you pay attention. I highly recommend taking his class.
Wojciech Czaja MATH141 Expecting an A gmichali 08/17/2009	This professor is fair. His tests are extremely polar (5 questions on each test); there will be one really, really easy question that will recieve NO partial credit because it is just that easy. Meanwhile another question on the test might be quite difficult. The other questions will be somewhere in between. Has an odd sense of humor. My test scores were a 94, 59, and 67, my quiz avg. was likewise around 78 (after dropping 2 lowest), and I got 160/200 points on the final. Somehow came out with an A-. Take MATH141 with Czaja. His lectures are average. I stopped going after the 1st (of 3) tests. He drops your lowest of 3 tests, 2 lowest quizzes of 7 quizzes, and lowest 3 (of 13) homeworks. You only need a 60% overall for a C, 50% for a D, 75% for a B, and 90% for A. Overall, this professor is very fair, much more easy going than the other Calc II profs. I mean come on, you need only a 60% for a C. Take this class if you want to avoid Francis Gulick, Ray Johnson, or even the great Denny Gulick also.
Wojciech Czaja MATH141 Expecting a B joepenn1 05/01/2009	Czaja has one of the fairest grading systems where 1 test, 2 quizzes, and 3 home works are dropped. Loves the theory behind Calc 2 but usually only uses examples from the book. I got a C because I only did the Webassign and no additional problems on my own. With that said if you understand the basics of Calc 2 material and do the practice problems/quizzes he puts up you will do fine. Lecture attendance is person to person basis depending on how well you know the material. I'd go though.
Wojciech Czaja MATH141 Expecting an A Anonymous 01/22/2009	Czaja is probably one of the better professors for math141. Exams, though challenging, are actually quite fair. He has a grading system where you are allowed to drop an exam, 2 quizzes, and 3 homework assignments. He is very fair and understanding. Though his lectures may seem dull, he is more than happy to answer your questions if asked. He has a lot of safety nets for those who might fail the course. If you truly work hard and do problems from the book (not just webassign), then there should be no excuse for anything lower than a C.
Wojciech Czaja MATH141 Anonymous 12/20/2008	I would highly advise that you not take Calc II with Prof. Czaja. First, his accent is understandable, but can be quite annoying. Second, his lecture comes right out of the book, so you don't get the benefit of additional examples. Third, his exams and homeworks are downright rediculous. The homeworks are extremely tedious to complete, and often on topics you don't need to know. Furthermore, the tests are extremely difficult, and test the smallest details of the course. For example, one test was on the chapter involving infinite series, and there was not one problem involving Taylor polynomials/series, which is a major part of the chapter. Instead, he tested on the stupid little details that no one remembers. If you are forced to take this guy, going to class is really not necessary, just study and do a ton of examples, and you can probably scrape by with a B.
Wojciech Czaja MATH141 Expecting an A tallboyt 12/18/2008	He is a good teacher and don't be alarmed if all you do in class are proofs b.c that's normal. He drops 2 quizzes, 3 hws (from online) and 1 test. He is helpful from the fact he gives a prac test b4 an exam which is almost alike. He gives lots of prac that will be on the final. from easiest to hardest: test -> quiz -> webassign. good class overall.
Wojciech Czaja MATH141 Expecting an A Anonymous 12/18/2008	Czaja (pronounced shy-ya) is an interesting professor. He cares that students actually understand the material, and unlike other professors that I've had, he will step back in lecture and remind you of the "bigger picture" behind Calc II. Czaja had a fair grading system: he lets us drop an entire test (1 out of 3), 3 out of 13 homeworks, and 2 out of 7 quizes. The final exam is worth a lot, and he puts a lot of emphasis throughout the class on its importance and weight (200 pts out of 600pts of the grade). I did not find him to be an amazing lecturer, but I wouldn't say he was bad either. Overall, I think Czaja is a good professor, and I would recommend him for anyone looking to take calc III and higher level math.
Wojciech Czaja MATH141 Expecting a C Anonymous 12/03/2008	Odd professor in some ways. He was a good teacher, but he made it difficult. Wanted us to learn the material on our own as much as possible, only because he truly wanted us to learn the material and this was the best way. Fairly hard exams, very hard HW, not an easy professor, but is a great professor to teach you the material and prep you for Calc III and on.
