>what was the most difficult part of the course
Being able to come up with integrating factors by inspection, trying to wrap my head around "variation of parameters."
>were there any "gotchas" that got you during the semester
Maybe not a "gotcha" but like a couple weeks into the course and realizing why lin alg is taught alongside ODEs (common in America). Also, the Wikipedia explains VoP better than any text I was ever prescribed in school.
>do you have any general tips or advice for someone starting the course
In the words of a controls professor quoting his math teacher of some couple decades ago: "Solving a differential equation is glorified guesswork." Don't sweat it it, it's largely a memorization game. I recommend putting more effort into understanding and learning the various numerical methods (of course, you still need to pass this course, anon). Obviously, do lots of practice problems.
