@Phantomlink How is your class organized? For mine there’s a teacher but we only learn by reading a textbook. We have to do these super complicated projects and the teacher isn’t much help. I thought the class would be fun, and I wanted to learn more about computer science since I know basically nothing, but I’ve been miserable in the class so far.
So in my personal opinion, I think AP Computer Science A is hard. It’s harder in my opinion than honors pre-calc at my school, which is supposed to be the hardest math class (even harder than AP calc AB.) It’s not really the tests that kill me, but the programming assignments. There are so many we do in such a short time that it’s hard to do it 100% right in the way she wants, and it’s a lot of problem solving. It doesn’t help that the teacher and I do not have a good relationship (she doesn’t like me.) She kind of has a reputation for being rude to students, unless she see’s that you’re really good at CS. 
Just a heads up, but this is coming from a kid who does a lot of self-study CS stuff on the side. Lol I don’t recommend taking this class unless you have time to devote to it.
