Affiliate Marketing Secrets

I live in Philadelphia. I’m trying to find a major in web development, not so much the design part (wouldn’t mind it, though) but the coding (php, jquery, and all of those fancy stuff including basics like html and css, etc.)
The only college/university I could find was Drexel, but Drexel is a private university and it’s EXPENSIVE. I need to attend a state affiliated college but I can’t find one with the major I want. I talked to my counselor and he seem a little clueless about web development.
