Need some help.

Soon, I will be able to take AP computer science. Should I? If you've taken it, what was it like? I'm just worried it will be like some shitty "Scratch Class".

If it's anything like mine, it is nothing like Introduction to Programming... It's a serious class that actually challenges you.

^ I heard the same thing so I didn't take it.

Well he also made a rage thread about learning Java...

[Cataclypse]

For my class we did Scratch for a few days and dived right into Java afterwards. I would take the class but my teacher is an expert so I may be biased.

I don't like Java. But, I've done some small things in it. Anyways, thanks for answering. What do you mean by challenge though?

[Hunter's Panda]

I am interested in this as-well, I just started C++ :P

"challenge" in the sense that it's new material that you get drilled into your head, you either learn it or fail.
GG NO RE

shit like this:

int numerator = (Math.abs(gen.nextInt()%ENDING_NUMBER) + STARTING_NUMBER);

or here's a fucking fantastic one...

Sounds like Intro to me...
In Advanced (Or AP...) the teacher assumes you know what the fuck you're doing and know what an IDE is, so we began with a simple number guessing game.

I'm taking the test this May for it.

I recommend it if you can have a good grasp of programming logic and mathematics.
