Get your parents to get you alot of production and graphics software(unless you can afford it, it can be a bday gift)
And PRACTICE, 65-80 percent of everything you learn is by experiencing it. So get some software and start skinning/modling/coding. Whatever you want.
I have a Computer Science BcD from a 4 year college, and I can speak from my own experience. I taught myself to code in c/c++ and dozens of other languages just by playing around with the code and stuff from existing programs. Have fun and you'll enjoy yourself and what you're learning. Trust me, otherwise you'll burn out from all the study and never want to code again.
The classes are just there to focus your knowledge and prove your skill, go and pick the coding courses with some background in logic math(NOT Calculus, that does jack for you until later on).
The classes that most bored me were those damn Logic Math and programming math classes. Ergh. In, Out tables AND/OR/NOR logic, ahahahahahahaah*crazy dance*
Good luck.
