Fall 2016 - Andrews is a really great professor. His lectures are generally engaging and he does very useful examples in class. His tests are like the more difficult homework problems and are generally manageable. If you can do all the problems in the homework you'll be fine. His final was slightly more difficult but if you do enough practice, you'll be fine If you need the textbook for cheaper price, contact 310-913-6851

Spring 2016 - The lectures are dry (as almost all math lectures are to me), and the professor is very heavy on the theories. He spends most of the time explaining how formulas are derived, which is interesting but doesn't help much with the homework. Just going to the lectures definitely isn't going to get you a good grade. Some things that helped me: 1) Going to discussion sections: the weekly quizzes were ridiculously easy, but they kept me studying. My TA, Kwon, was really helpful--during the review sessions, he would go over especially difficult problems that are similar to the ones on the exams. 2) Test bank: Aschenbrenner gives out the solutions right after you turn in each exam, and you can easily find previous exams (which gave you an idea of what to expect) at the test bank. 3) Practice problems from the textbook: solutions to the textbook are available online, use them to check your homework. If you don't know what you did wrong and why, you will just repeat your mistakes on the exams. Overall, this class wasn't as difficult as I expected (while I definitely did put in extra work). It does help to have a solid foundation, like being familiar with all the basic calculus properties. For reference, I took Calc AB in high school and got a 5 on the AP exam. The quarter system schedule is still rushed, but some topics from Calc BC (vectors) aren't even covered in this class, so don't stress out too much--the class is definitely doable.

Spring 2018 - Overall, this professor was decent a did a good job teaching the material. Although my background in math was mediocre at best, she really did try and teach calculus in a way that was easy to understand. In addition, she also made her tests as clear and concise as possible and graded the class on a curve. I would take another class with her again.

Winter 2017 - This professor is EXTREMELY EXTREMELY difficult. As you all know, Math 31A was just a review. Biskup expects you to be a master of 31A so when you first arrive to class he throws at you insanely difficult homework which can only be done if you go to his office hours. And you can't take notes at those office hours. The medians on the midterms were around 40 and there are 3 of them. Although, this class is only 4 units, it takes some serious effort to pass it. If you do decide to take this class, do the homework. Know how to do EVERY SINGLE problem without any aid and go to his office hours. Do not make the same mistakes i did.

Fall 2019 - THE ONLY PROFESSOR YOU SHOULD NEVER TAKE A CLASS WITH. TRUST ME. I'm a math major and I had to work my ass off to salvage a B. Plus, the guy is a dick. On the first midterm, like 50% of the class got an A- or more, so he announced that too many people did well so he was gonna make the second midterm MUCH tougher so that people wouldn't do well. He is the ONLY professor I have ever met who WANTS the students to fail. Honestly, I have ZERO respect for this man and I would never wish this hell upon anyone.

Math 31A and Math 31B with him. I got at least 3 or 4 past Brown midterms or finals before each midterm and final in this class and the ones I took with Brown this year (10F 11W) have been much much harder. He does recycle the type of problems but just makes them a lot harder or puts them together somehow. It isnt impossible though, I studied for 3 weeks straight for the final and got a B on it. I rarely went to lecture because he would spend most of the time doing proofs, and would end his lectures halfway through sections and also he would teach you the material with the hardest example of that problem he could come up with instead of showing us easier ones and progressing from there. I used the site patrickjmt to teach me all about series and other info I wasnt sure about and I was familiar with the material from taking AP Calc BC in high school. Also study your ass off for the final because its 50 percent and by far the hardest test. I learned that the hard way by going from a solid A to a C+ from the final in 31A.
