Have you talked to the faculty about this? If you can show your professor that you know everything he is teaching, I'm sure he will help make it challenging for you. Ie either by giving harder assignments where you'll learn more or he wont take your attendance and let you sit in on some other advanced class which you'll find more challenging. Do NOT leave school. There's no other place where you'll find smart people who are paid money to teach you the stuff that you want. And those grades will make a huge difference in your income and how your viewed when you go in for a job. Ask for help with your problem from the sources available to you and you will get it. It might take a few attempts to get to a professor who understands your situation but it will be worth it.
