Had an amazing time studying PHYS273 over the summer with prof. Hailu. The course was straightforward, the material he went over was quick for me to grasp onto, the TA was very accessible, the Homework wasn't difficult and same with the midterm. If you have to get your credit for waves over the summer, I strongly recommend taking it under him, you will not regret it.

People here are saying he's boring, but honestly, there are worse things. He knows what he's talking about in and out. His teaching style is clear and he is patient with any questions that are asked. He was accommodating, when people were having trouble seeing the blackboard he switched to the projector in the next class. He does a lot of examples in class. If you do/understand those with him, it's a huge help. Quizzes are not that bad. Midterms were hard but not a crazy level of hard, especially because you get an entire sheet of paper. I would take him for the rest of my physics classes if I could.

I'll be honest I came into this class having done physics a few times before but being pretty bad at it. Content is almost exactly what one would learn in AP Physics C mechanics, honestly wished I paid more attention then. First exam is pretty easy but it gets harder from there, even then I felt his midterms weren't that bad. On exams he does allow you to bring a one sided cheat sheet, so I found that to be helpful. Discussions were honestly the worst part. There's a quiz pretty much every week in discussion in the last 10 minutes of class, and obviously you would want to focus on that content during discussion, well you would be disappointed because our TA at least would just go over stuff from the next chapter and spend all of class doing maybe 2 or 3 problems even going into the last 10 mins. I tried really hard to pay attention but it was tough to follow along. Getting exams/quizzes back was very disorganized and we never went over any of them. Grading also took really long. This semester all the office hours were online and I tried going to one once but it seems the TA stopped holding them halfway through the semester, so I was pretty much on my own. There was some in person tutoring thing in the physics building I went to once (I did go day before hw was due so maybe that's why) but it was packed and the tutor wouldn't just answer the question and no one got it for hours, I ended up just figuring it out myself later. We also got assigned a homework to complete every week, and it's pretty long. I would definitely recommend starting early (at the minimum a day or two in advance) because trying to do it all at once is really hell. I would also recommend finding people in your class to work with because it makes it easier and helps you through it emotionally as well lol. Last couple hw problems of each set were pretty hard in my opinion and def harder than quizzes and midterms so I would just try and answer it and move on without devoting too much time to really understanding. We used expertTA which could sometimes be really stupid and confusing but it does give you 5 tries, no points deducted, and the feedback can be helpful if it gives you any. I will also admit I sometimes skipped lecture, sometimes fell asleep in class, or just did not focus in class and here's what I found to be the secret to doing well. He goes over problems in class and posts the slides online. DO THOSE PROBLEMS BEFORE MIDTERMS AND QUIZZES. Follow along with the work to those problems and try understanding why those steps were taken. These problems seemed to be the most on level and usually weren't too bad. He does "post" the slides online but there's no answers. It is possible to find the answers to those problems online but sometimes its more confusing. I would recommend going to class and just writing down exactly what he does on the board even if you don't get it in the moment (sometimes I just took pictures but I ended up losing them in camera roll or just not looking back). If you keep this organized you can use it to study and it will help you a lot. Sometimes looking at the textbook may be helpful if you don't know a concept at all or you can try looking at videos online. For exams I did that^ to study and wrote down all the equations and anything I would usually forget on my cheat sheet. I got an 88, 84, and 95 on the midterms this way. Most people fail the last midterm but I studied for like 7 hours at Mckeldin (probably shouldn't take that long but I get distracted easily) for it, looking over all of that^ for each chapter on the exam. I still never felt very confident after exams but I always answered each question and showed work because he does give partial credit. There's usually "3 questions" on the exam but each has like 3 or 4 parts and some parts were not even related (pretty much different questions). I did end up working pretty much till the end of the allotted time for every exam. The final exam in my opinion was possibly the worst exam I've ever taken in my life. I had 2 exams that day so maybe that's also why but I was sure I failed. He allows a double sided cheat sheet for this and I wrote every equation that came up but it honestly wasn't super helpful. I probably could have studied more but I pretty much just re did all 3 exams and tried to really understand how to do everything (if you can get your hands on someone's past exam where they got everything or nearly everything right, USE THAT, because just going off his "corrections" is not good enough for figuring out how to do the problem and google did not help). I would recommend going over quizzes as well but I lost most of mine or just didn't get them back, and lastly look over the slides questions, and then if time do textbook stuff. The actual exam was "6 questions" but again they have parts. All of the questions were pretty hard in my opinion but I did attempt everything, and honestly BS'D my way through most of it. He looks at partial work so if you know how to do one thing and not the other just come up with something and use that in the part you know. I ended up actually getting a 71% on the final so... I had a 92.5 before the final was put in and then it went down to an 87% after. Hailu does not curve exams but he does drop your lowest quiz grade and if you're sick you can be exempted from one quiz as well. He does end up curving the class at the end so 20% of people get A's (A-, A, A+) all included, and after the curve my grade went up to an A-. What I've heard from people in the past is that after the final grades go up by ~5% so a B+ becomes an A-, a B becomes B+, B- becomes B, etc. To wrap this up, this was my hardest class in my first semester in college so maybe my view is skewed but I think physics is just a hard subject overall. I've never had a good physics teacher to compare this to but this class has more to do with the amount of effort you put in than anything else. If you've taken physics before like me you can get an A by just putting in work when needed and hoping for the best. If you have never taken physics before I would recommend maybe doing AP mechanics stuff over the break before and putting in a lot of effort and time into this class. Good luck to all of you!

I think this is one of the few professors where the TAs are much worse than the professor, and not in a good way. As other reviews stated, he's very boring and spends class deriving equations and solving problems. Don't take him in the morning if you don't get much sleep, you might doze off. The TA I had was horrible, always late to discussion, took long to grade, and get aggressive if you asked questions how she solved a problem.

I literally could not make it through Hailu's lectures without falling asleep because he speaks in a monotone and is so disinterested in his own words. Eventually, I stopped going to lecture and taught myself the material. I actually was doing better in the class this way until I bombed the final because it was a common final exam and was completely different from Hailu's midterms, quizzes, and homeworks. There was no good way to prepare for midterms or the final because students are given no practice problems, no old exams, no feedback on anything you submit, nothing at all to give any vague idea of what an exam problem might look like. Also, I had to speak with Hailu on two different occasions about special circumstances that affected my ability to do work, and he was cold and unsympathetic, providing the bare minimum accommodation of one make-up quiz, then not telling me what the quiz would be on so that I ended up with a zero on it because I had no idea what to study.

Hailu is fine as a professor. He tends to get frustrated with students who ask questions in lecture which makes it a hard environment to be in when you're confused. The reason this rating is so low is because the TAs for this class were absolutely terrible. They take up to a month to grade quizzes, and don't know what has been introduced in lecture. Multiple times my TA has done in-depth practice problems in discussion on a topic that students had never seen before. Exams also aren't graded with feedback. You just get a little x next to your answer with no notes, meaning that you lose points but don't gain any knowledge from messing up.

Hailu is decent, pretty boring, but decent. He goes very slowly through the material, so we wound up around two weeks behind the syllabus by the end of the semester. The slides are usually easy to follow, but he'll occasionally go off onto a separate screen and start deriving an equation or something, which we often don't need to know. He spends a lot of time going through example problems in lecture, which is somewhat helpful but wastes time since he goes so slow. There are weekly homeworks on Expert TA with 10 or so problems, usually a couple of which are quite hard. He doesn't take off points for incorrect attempts though, which is great. There are also weekly quizzes in discussion which are really easy, save for a couple hard ones, but you'll always get the equations and constants you need. Discussions themselves aren't that helpful, the TA will just go through a bunch of problems from the textbook and that's it. Most people just left after the quiz was over. There were only two midterms which were not bad at all, and you get to make your own formula sheet for them. The averages were in the high 70s/low 80s. With the homeworks, quizzes, and midterms all being pretty manageable, you could build up a strong grade buffer for the final exam. The final was slightly more challenging than the midterms, but still doable. There were 6 questions, but we only had to do 5 of them, so you could just skip whichever one looked the hardest. All 260 professors use the same final, which made me quite worried since Hailu was pretty far behind schedule, but there wasn't anything on there that he didn't cover. Overall, Hailu is fine and he makes 260 straightforward, but he's just a bit dull.

Some may say his lectures sound monotonous. This is true and he speaks so incredibly slowly—still, I think they were good quality lectures that were easy to understand and had plenty of examples. His quizzes are easy and exams are fair. He typically will curve the final grades to a B- average, but since our class average was already doing this well, we didn't get a curve this semester.

The most cold-hearted and cruel professor that I have met so far. He even made the expectations of us learning online being higher than in-person settings. For some weeks, he made the HW problems extremely difficult and he didn't care if most people are immensely struggling. Instead he always would say that these problems are easy and made people feel even worse. He basically doesn't know how to show empathy towards his students and. If he would help us out, then everyone could be benefited that way!

He’s both ok and extremely boring. If you’re ok with listening to boring, monotone lectures that give the information necessary for homework and exams, then go with him. His exams were mostly ok, but the final exam seemed way harder than necessary. If you need an ok professor, then he’s your guy.

I had him during fall 2020, so class was completely online. His lecture videos were somewhat monotonous but actually taught you the material if you paid attention, and he had good examples so I never felt the need to read the book to supplement in-class instruction. Make sure to watch out for numerical mistakes in his examples though! Quizzes were simple FRQs which reflected the main concept of the content for the week, and homeworks were pretty consistent with what was taught in class. (Some problems were hard, but that's normal). Midterm exams were pretty ok, final was really hard, but the curve takes care of it.

Hailu is absolutely awful. His lecture videos are mind-numbingly boring and his ego is off the roof. Don't bother emailing him unless you want a snarky response that makes you feel stupid. His final exams are also incredibly hard, leaving everyone to wait anxiously for the curve to save their final grade. Save yourself and find a different prof

Dr. G is a very fair professor. His lectures are monotoned and slow, but his lecture videos are simple and easy to follow. The homework goes well with the lecture content but may get stuck on a few which is normal. Dr. G's quizzes are very fair and relate to the previous lecture content as well. He provides the equations and contents needed, so as long as you complete the homework (or most of it) before the quizzes, and are caught up on the lectures you are in good shape. Exams are fair, but studying with book problems does help. Book problems are more challenging than exam problems but are a good tool for understanding the content more.

*class was fully online due to covid* Imagine learning physics by reading a textbook. It's informative, but not particularly exciting. Now turn that textbook into a powerpoint. Literally just screenshot the equations from the digital version of the textbook and stick it in a powerpoint. Mix in an excessive amount of practice problems, usually solved wrong and usually easier than anything the test will give you. Now have a man read this powerpoint, veeerrryyy slooowwwlllyyy, unconstrained by the normal class schedule due to the asynchronous format of the class online. Thats Hailu. Looking back, I'm pretty sure that if I skipped every lecture and just read the textbook, I probably could have learned the same amount in half the time. The class had quizzes every week over zoom. They were timed for 10 minutes, so if you had internet issues, you were kind of screwed. The quizzes varied wildly in difficulty, from high school trig to problems we haven't learned yet. The class uses expert ta for all homework, which is actually very nice. It gives you hints and specific feedback if it knows why your answer is wrong. The class is curved, but hailu seemed to be deliberately vague about how much, or whether he would curve down if final grades were too high. In the end, the 67% average on the final meant there was a generous curve up of at least a few percent. Ultimately, take Hailu if you have to. He's not necessarily a good teacher, but he's also not actively bad.

I would give him 0 if that was possible. I think he doesn't deserve one dollar of his salary. He posted the lecture videos and never held class once, only proctored exams and quizes which is so nice of him honestly. He also never ever gave any study material for any test.

Professor Gebremariam is one of those professors that you can just tell that he is being forced to teach students, which is clear when you email him, as he talks down to his students and acts like he is gods gift to physics. His lectures are mind numbingly boring and pointless. To make it even worse, the TA that i had was somehow has worse Hailu. Would stay away from this professor if possible.

Hailu's style of teaching mechanics is by completing examples during lecture, so if you do not make the effort to attend, you will likely have a hard time. He's a pretty laid-back professor and likes to occasionally joke during class too. His home work assignments are pretty easy and only take around one hour a week. He is not a perfect professor and definitely will not make you love physics if you already don't, but I would recommend him in general.

He is the definition of an alright teacher. You will get in what you put out and his exams are fair representations of the material covered in class. I do advise you work out a significant number of problems in the book, since just doing the ExpertTA homework is unlikely to earn you and A unless you have past experience with physics. He's a good guy and writes very clearly. Lectures consist of mainly slides with supplemental work on the chalkboard.

Hailu is a fantastic professor and I definitely recommend taking his class. He is very careful in explaining complex topics accurately and makes few mistakes in lectures. His exams were incredibly easy (except for the final, which was not as much difficult as it was time-consuming). If you pay attention in lecture and try to understand the content, you should have no problems.

Whatever you do please don't take this professor. Three exams, doesn't drop any, doesn't narrow down on topics covered in the exams he will say to "study everything" which is no help at all. His lectures are super boring but he does do a lot of example problems which help a little at first but definitely doesn't prepare you for the exams. His exams are such curve balls there's aways one problem that will throw you off and he gives like 2 problems, so if you screw up one, you fail. He curves a lot at the end but you gotta have at least a 70% or higher to get a B. Which isn't bad but his exams are bad so that might be hard to get. The course isn't bad as long as you read the textbook and do practice problems, but just make sure you have a good professor.

By far one of the worst professors at UMD. He teaches via PowerPoints and uses the simplest examples in class, and then when the exam time comes nothing is the same. The exams are much more difficult than anything offered in this course, although you can expect a 10%+ curve at the end of the semester. nevertheless, I would not suggest you take him unless you have to!

He's a pretty decent professor even though most of his teaching is based off his slides. His TA is pretty bad however, and discussion sections are basically useless aside from the required quizzes.

In my experience in all 3 general physics classes here, I thought Hailu was the most well-rounded when it comes to teaching the material and going through examples in class. Although the first exam is pretty hard, he lightens up the second and third exam. He also curves the class on average 2-3%.

Bantu makes PHYS270 a decent experience. There are two midterms, each worth 12% of your grade, which is nice because most of the PHYS270 professors do 3 midterms. Overall, they were pretty easy, with a few of the questions being very similar, or even direct questions from the homework. Lab is 25%, but that is the same regardless of your professor. Lab was, in my opinion, the worst part of the class. There are only 4 labs (plus the culminating lab), but they all pretty much took the full 3 hours and were pretty tough. Your experience is going to depend entirely on who your lab TA is. If you get a good one, lab shouldn't be bad. Quizzes are 10% of your grade, and there is one at the end of each chapter. He does not announce the quizzes beforehand, but if you follow his lectures and the schedule, you should know about when they will be. They are almost always very easy and require only basic knowledge of the chapter. Write down the equations as he is teaching, or start the homework before he finishes the chapter, and quizzes will be simple. Homework is 21%, with 14% being masteringphysics and 7% being written. The written is just to do 3 of the masteringphysics problems by hand on paper and turn it in, so it's not really extra work. The masteringphysics tends to be pretty easy, so the homework isn't a huge burden. Do check often if there is an assignment though because he does not announce when he posts them. Do not copy from the solutions manual because they are watching for that and a large portion of the class did just that on the first homework. The exams were each 3 problems and were usually pretty simple. The only issue is that since they are only 3 problems, if you are completely lost on one question, you already lost a large portion of your grade. Study hard for these, redo the masteringphysics, and you'll be fine. The final exam was a common final across all the sections, and was actually pretty easy. It's hard to say if he curved the class because we did not get our final exam scores back, but I have a feeling that he did.

To be honest, the only reason I ever went to lecture was because of the unannounced pop quizzes. Bantu's lectures are pretty boring (and that's with a laptop). Mastering Physics (online HW) is more difficult than any of the tests (or the examples done in class). If you have even marginal experience with physics this class is a review. (but a 3 on AP C Mech doesn't place you out).

This guy isn't that bad, but he isn't that good. He should illustrate some more example problems. Instead, he primarily just uses Power-Point slides which are identical to the book, so if the book confuses you Bantu won't help that much. Also, I didn't like that he gives no sample exams whatsoever; on Fri. before a Mon. exam he just tell us "3 problems 1 is on Chap 35, 2 is on 36, 3 is on 37". However, his exams were really straightforward, everything was an example in the book or an assigned homework problem - no curve balls.

Bantu is a really nice guy and a decent lecturer, although he can be kind of boring. He goes through the material pretty slowly, which means his tests end up covering less material than usual for 270, so they are not very difficult in general. He grades very fairly and I think there was a curve at the end of the semester. He usually does one pop quiz a week, but the questions are so easy (as long as you have the equations written down). The Mastering Physics hw is not too bad, especially since he gives you 5 chances to answer each question correctly, with no loss of credit until the last chance is used up. The only really annoying thing about Bantu was that he never emailed us when he posted assignments, so you basically have to check Blackboard constantly to see if there is a written assignment and you have to check MP to see if there is a new online assignment. Overall, Bantu is definitely one of the better physics professors.

Dr. Bantu is a very nice, easygoing professor who made PHYS270 a relatively easy experience. He's a rather dry lecturer, but he cracks jokes in lecture occasionally to wake up the many sleepy, bored students. However, his class was not too hard., especially compared to the other professor, Jenkins. The tests were straightforward (except maybe the second one, which almost no one finished), and the final was not even cumulative! MasteringPhysics was the homework system used and there was always help available if you knew where to look. There were quizzes in lecture at the end of each chapter, but most of the time you did not really have to go to lecture since he posts lecture powerpoints online. Also, discussion is useless. My TA always went on tangents that usually ended in him talking about Maxwell's equations, which was irrelevant to most of the topics we were covering. The worst part of this class is the lab which counts for 25% of the 270 grade. Fortunately, we only had it every other week, but my experience was awful since no one knew what he or she was doing and the TA couldn't speak a word of English and explain anything! Overall, definitely take Bantu over any other PHYS270 professor!

It only requires V5 but actually uses V3,4 and5. Does not make sense to buy 3 books. Try the full volume(ISBN:0805389601)! It will be a lot cheaper.
