At first this course felt like it wasn't significantly harder than MATH100. About a third of the way in I wanted to quit. Keeping up with everything is absolutely key. If you fall behind, just drop the course. That said, having even a basic grasp on the material is super useful in tons of other math-based courses (PHYS111 for example), so at the course is somewhat useful.

The course covers the basics of integration, series and sequences, complex numbers, and polar coordinates. Integration in particular came in handy in other courses, as well as an understanding of some series and complex numbers. I personally found integration to not be a huge jump from MATH100, but once we moved on to series it felt less related to what we had done before.

Andrea was amazing. He broke concepts down into tiny understandable pieces, which made most of the concepts seem somewhat less daunting. He also did lots of fun examples and added tons of little doodles to his notes and could make some pretty good jokes related to the material. His handwriting was absolutely atrocious though. Missing lectures was a bad idea because his posted notes were barely readable without knowing the words he said as he wrote the notes.

Take the homework seriously. It's one of the best ways to determine if you know what's happening, and if you're consistently doing poorly on the homework or skipping it entirely your exams won't go well. Also, make sure you have a firm grasp on precalculus. Polynomial long division and completing the square came up all the time, and if you don't know how to deal with those you'll get pretty lost at some point.
