It's a good thing you've figured this out already, but boy is school going to be painful from now on. Everybody else is probably going to tell you otherwise, but perhaps you should consider a radical change in your education plans, especially if things just get worse. Maybe leaving in a couple of years and doing something more worthwhile, even if that just means going to college early. I know it sounds risky, and others reading this might even think I'm being irresponsible in telling you this. But I'd at least keep your options open.
