Running start gpa vs. college?

I'm a senior in highschool in the running start program. I only registered for two classes, Step Aerobics and Pomology (a agriculture fruit class). I happen to hate the pomology class but it is now the week of finals and I keep sleeping through it on accident and am worried I might get a low grade. However, the University that I transfer to next year apparently is very picky about the credits they allow to transfer. So should I be worried about getting a bad grade since it probably doesn't matter?
