Those three words make me sadder.

Don't worry, multi variable calculus is way easier when you get there

I already took MV. I'm doing differential equations now.

What are you doing decomposition for in diff eq? I guess are you in ordinary it partial diff eq? cause I never did partial.

Yeah. It's for finding Laplace transforms and working with discontinuous forcing terms.

Can't say I've done that yet, I don't have to take partial for my degree.
