Hmm, grades are important but just as good old Albert had said… Science without religion is daft just as religion without science is blind. Those parents of yours, Robin, want you to be perfect in one single way, grades in this case. They don't seem to understand that no matter if you had all the best grades in the world, they do you nothing if you don't have a life to go with them. ;) Do what you need to do and take care man.
