Welcome to the forums! You have to be at least 16 I believe to solo an airplane and at least 17 to get your PPL ticket, 18 to get your commercial. Qualifications for the private are I believe 40 hours total time, 250 for the Commercial. Lessons out of your local airport will probably run around $100-ish an hour. As far as education goes, start with graduating HS, then worry about college if you want to do that. My biggest regret is that i wish I had started when I was your age, but this is a great decision for somebody your age. Good luck and keep up with the questions!
