Course material builds on itself. Try to take it 1 semester before fluids so that you don't forget everything.

Professor really cares about her students. Quizzes largely matched hw assignments. Final project was fun.

Do hw even if it's optional.

It’s not too difficult, you just need to keep up with the work load which isn’t that much compared to other courses.

Great professor who really cares about the students, explains concepts well, gives extra credit, and a fair grader.
