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 - I took this class Fall Quarter 2025 and received an A. In comparison to the other professors teaching this course, Professor Arant is an absolute gem—you NEED to take his lecture if you want the best shot at doing well. His lectures are a bit fast-paced, and I’d sometimes fall behind on the notes, but his examples and theorem explanations were so clear that reviewing them later + watching a few YouTube videos was enough for me to fully understand the material. I didn’t take Calc BC (only AB, which I got a 5 on), and while BC students definitely have an advantage, most of the content was new to me and I still performed well. Lectures aren’t mandatory, but people who had other professors would literally come to his lectures because he explains things so well. Homework is assigned but not mandatory—you definitely need to do it if you want to do well. If you’re ever lost in the class, he posts his notes online, there are tons of YouTube videos to help, and both he and his TAs are very helpful in office hours. We had 5 quizzes, but they’re take-home and you have the whole day to complete them, so they’re pretty chill. There are 2 midterms and 1 final. Midterm 1 was very straightforward and the questions were all fair—class average was around 50/60. Midterm 2 was an absolute trainwreck (class average: 41/60). I got a 100 on Midterm 1 and then a 67 on Midterm 2. It was significantly harder, and some questions required really niche applications of convergence tests to get the correct answer. This class isn’t easy, but with the right amount of work, an A is definitely achievable. Professor Arant was great and I would definitely recommend!!

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.
