Has anyone here taken college animation classes? was it difficult?( more difficult than other classes?)

I was considering getting a certificate in animation but it requires me to take 4 dual enrollment classes at once, so far I've only taken two and (as you can see from my grammar) i'm struggling with my English class.

I've taken a film class and loved it, I love animation more though and I'd like to take the classes without ruining my GPA..
