Overall, and compared to Calc 2, I found Calc 3 slightly more tolerable. The concepts, though conceptually challenging, felt more understandable than calc 2. Exams were just as hard however and would recommend a lot of studying beforehand.

I really like my professor. He was great at explaining three-dimensional concepts and would actually go over some of the things we needed in the homework.

Manage your time. I was doing pretty good earlier in the semester but towards April, I started letting things pile up. Just stay on top of your studying and make sure you understand each lesson before going on to the next one, they all build on each other.

Even though I didn't have him, Chen is one of the best if you can get him. Very clear lectures, but even if you don't get him you can still watch his recordings for clarification.
