One of the worst teachers I’ve had the displeasure of taking. She often fails to explain things clearly and then blames the students even if she makes the mistake. There is no regrades and no arguing, and her grading is beyond absurd. You must complete every problem exactly as she does, correct alternative solutions will yield you zero points. While the class isn’t that difficult, she makes it immensely frustrating as you can do a problem 90% correctly and make small numerical errors and get no points. The exam averages were in the 40% after curves, and while the problems are similar to the HW, she often changes the numbers in such a way that a completely different method is required to solve them. You are allowed a formula sheet, but even though she isn’t clear, she will give you a 0 on exams for the smallest dubious infractions. The final exam does replace all grades, so getting a decent grade isn’t that hard, but once again it is just not an enjoyable class. Take it if you need it for the math major, but just be prepared for a very unpleasant experience.

Professor Ren was great, the class was very challenging but I learned so much math and I came out the other side feeling very confident in my statistics ability. She is harsh with homework and test grading, but the curve is very generous, plus she's just a great professor!
