Fall 2017 - Killip is extremely knowledgeable and very approachable--definitely go to his office hours! He's super nice and will always answer your questions, plus he provides good hints to homework problems. His lectures are also pretty useful (he explains the material pretty well) so I highly recommend going to class--especially because he likes to go in depth on material that sometimes the textbook just briefly touches on. What helped me a lot was reading the textbook and watching the relevant Khan Academy videos on the section before he lectured on it--it made lectures a lot easier to follow. He's also pretty funny, which definitely makes class more fun. Also, note that his homework is 1) insanely difficult and 2) quite time consuming, but it's really good preparation for his exams and honestly I'd say his exams are at least somewhat easier than the homework. Overall, I give Killip 8.5/10 for being an excellent lecturer, very approachable, and funny. His homework is actually horrible though, it's pretty hard.
Winter 2022 - The thing I liked most about Prof. Killip is his tendency to use simpler words instead of formal vocab. His energetic lectures made this class my favorite calc class. Exams and homeworks felt pretty standard, although I did take this class in Winter 2022, which had COVID perks.
Spring 2020 - *I took this course with the online format due to COVID-19 Professor Killip was a decent professor. I thought that his lectures were sometimes vague and a little confusing as he tends to ramble while he gathers his thoughts. The HW was sometimes a challenge but was not too overwhelming. The quizzes made up a large portion of your grade and were fairly easy. The midterms and final were also very easy as the median for them was around 90% and mostly required computational problems. I think if you watch and understand the general ideas behind each of his lectures, you should do well.
Best South Campus professor I have had at UCLA. Amazing, teaches you every topic thoroughly, is very helpful at office hours. Goes over anything and everything without ever being condescending to his students. His exams ACTUALLY COVER WHAT HE TAUGHT IN CLASS. There is usually one tricky problem on his test, but he has to have that so everyone isn't getting 100s. But definitely take Killip if you are given the chance, the man is brilliant. I would do anything for him to be my father. TAKE HIM.
Fall 2020 - If you are the type of math student who loves math and math is your everything, take Killip. However, if you’re a regular person who enjoyed math 33b and is excited to take an upper div differential equations class FOR THE LOVE OF GOD DO NOT!!! take Killip. For one, his homeworks take AGES. The material in the hw is next to impossible to do unless you attend every office hour, the lecture and textbook material are only slightly related. His exams expand on the homeworks that are already a huge LEAP from the things he lectures on. If you end up taking Killip, camp out in his and the TA’s OH to get those homework answers. Lecture will not help you.
Fall 2016 - The homeworks are hard, which normally you would expect to spend a 5-6 hours weekly on homework. But the exams are generally easier than the homework. According to the TA, Killip is the best professor to take to truly understand the material. "He teaches you 200% of what you need to know compared to other professors. So even if you only retain 50% of what's taught, you've mastered 100% of the material for 170A." Would strongly recommend to go to his office hours and the TA's.
