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 **********

Fall 2025 - Prof. Arant is the better Math 31B professor. During lectures, some people might find his pace too fast. At times, it may feel like he's just solving problems on the board. For each midterm, you are allowed to use a 3-by-5-inch notecard, and you are also given a formula sheet of integrals of trig identities. The midterms are like the homework problems. The final had problems that tested small details that were not covered in the midterms. Recs: - Over the course of each lecture (and especially in discussion sections), try to reach a rough understanding of the greater concept (e.g., why we're doing this technique) before writing it down in your notes. - Each lecture period is 50 minutes long. Leave longer questions during office hours (OHs) or discussion sections. Prof. Arant is significantly more helpful during OHs and takes things step-by-step there. Advice for mistakes that I made, that I hope no one else repeats: - Each problem on a midterm tells you how many points it's worth. If a problem is worth a lot of points (e.g., 10 points), make sure the amount of work you do is proportionate to the point value. - Check over your answers; it's okay to use up all of the test time. It's better to sit there, look at the ceiling, and have your brain think about it than to leave early and regret it.

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.
