BUT if you’re well along in your high school career and don’t really have much time to work on your art skills, you might want to look into a liberal arts college- then you can take art classes along with other classes (sciences, language, humanities, etc.). That way you have a fall-back, but if you still really like art you can pursue it either at your college or you can transfer.

Some great art/design schools:

Parsons, RISD, Savannah

Graphic designers do a wide range of things. Many times, people who major in graphic design go into the advertising business.
