Advice please help! 10pts.?

Just my opinion here, but I would say stay in HS. A rigorous schedule with AP classes will help you get into college, regardless of how competitive your HS is. It's how competitive the colleges are that you need to think about. Do as much extracurricular stuff as you can to make your college applications the best they can be, keep your grades up, and you should have no trouble. Good luck!
