<p>Your SAT scores are great, as well as your extracurricular activities. The karate award seems prestigious, and I’m sure that will factor well… The C may or may not make much of a big difference, but if you show that you really improved (which you have), then I’m sure that they can let it slide. You seem to be an adequate match, but, just like everyone else here, my opinion is of course just an opinion. In either case, best of luck!</p>
