bad news

I stayed up three nights in a row studying for this chem test (it was at 8AM this morning) and I decided to get a power nap in before going. Forgot to set my phone off vibrate, slept through all but 7 minutes of the test. That's a zero, which has a couple of effects. Chem is my weakest class, so it pulls my grade down even further. I need to keep a 3.2 to maintain a few of my scholarships, so without them, because I doubt I can get a 3.2 if I don't do well in chem, I don't know if I can return next year. It looks like if I ace the last test(there are 3 of them) and the final both I would pull a 76, that's a C, and the only way to pull above a 3.2 is to get an A- in calc, comp sci and intro to lit. I need all three above a 90, AND I need to ace(perfect 100s) the last test and the final. I don't believe that to be possible, but I'm gonna try.
