I'm a junior in high school right now taking CS and AP CS next year. I plan on going to a University of North Texas to get my BS in Computer Science as well a certificate in game programing/design which I plan to use to gain a programing job for a game company. Assuming everything goes well I hope to move to game design after gaining some experience. My question is, is this a good path for me to take? I do enjoy computer science but my ultimate goal is design. Will I be able to go from programing to game design?

Yes, no problem. Have you read this forum's FAQs yet?
