Summer 2020 - I don't think the comments in bruinwalk truly represent Professor Salazar. He is really really nice and warm. He cares his students a lot. He explains things carefully and slowly in lecture. He has two quizzes every week but it is very easy as long as you do all your homework. Exams are easy and are based on homework.

Great Class, very effective and efficient professor. If you are taking this level of Math you should know what your going into. Calculus is a given in this course,esp. differential equations, you need it and you are expected to know it. The midterms aren't bad at all, it is very similar to the sample midterms he gives, average for first midterm was about 70 and 80 for the second, final was tricky but overall do-able. Study the sample tests he gives, and read the book! (the book is awesome, very clear) Also this class is very interesting real world applications. goodluck! Also the homework is free points, he grades by completion not by correctness.

Winter 2024 - Professor Tymochko is super nice and one of the most accommodating professors I've ever met at UCLA. She not only teaches very clearly in class but also posts nicely written lecture notes every time after class. Her homework assignments definitely served as good practice to help me better understand the materials, and she also gave us a 48-hour grace period for each assignment (which was super nice)! We also have biweekly quizzes every Friday (changed from in-person to online) and I think they also helped me better learn the content while keeping me on track. For our midterms and finals, we were only allowed to bring a notecard for our cheatsheet (which could be a little bit of a small space), but the tests are reasonable and nothing was super beyond scope. As long as you put in effort to listen in class and work on the homework, everything should be good. Professor Tymochko also patiently answers every student's questions during her office hours, and even asked us to fill out surveys to gauge everyone's opinions about the course workload and pace. Overall, I would definitely recommend taking the course with Professor Tymochko!!
