Good Job!
You are the mediocre smart kid. With smarts like yours, you'll probably be in the top 20% of your high school graduating class, where you'll take a mixture of Advanced Placement and honors courses (with the occasional standard class that you take for the guaranteed A or B.) Your teachers will see you as okay, and probably won't push you any more than you push yourself. After graduation, you will go to your state university. You'll get your undergraduate degree, maybe with honors if you really want to. Your teachers will see you as okay, and probably won't push you any more than you push yourself.
