Can a type B personality ever turn or change into a type A personality?

My plan for college is to be less shy, and not be as mich of a sociophobe. I hope I can do it.

It's easier to do that at college. I went from a introvert to an extrovert. 

Just be yourself though so you find people like you, then you'll love socialising with them etc.
