[Taken online due to pandemic] OVERALL The first 40% of the course finishes some multivariate calculus topics from Math 200 (Calculus 3). The rest of the course gives a basic introduction into differential equations (types of DEs, solutions to DEs, and various ways of obtaining those solutions). In many ways, the DE portion of the course feels like starting a fully new subject whereas Calculus 1-3 felt like a continuation of the same ideas. If you enjoyed the problem solving aspects of Calculus 1-3, you will likely enjoy this course too. I found the DE portion a little less satisfying than the Calculus portion because it was not as visual or intuitive (at least not at the level we learned it). Trefor is a great professor and ran a great course. I recommend taking it with him if he's a...read more

Beyond good lecture notes, make a neat equation sheet with quick notes about how to solve problems in each section. This sheet will be great for midterms and you can refer back to it when studying for the final. Attempt assignments early so you leave yourself time to ask questions in office hours.
