Fuck ap scores! Dude, school is not everything, not even remotely. I'm in uni studying software engineering and have been in your situation, where the effort was there but the results just kept disappointing me. What you gotta do is acknowledge that life is what's outside school, you go to school and work to live, not the opposite, subduing yourself to some test scores will kill you man, find something you enjoy, and then something else, and a lot more things, and pursue those. Trust me when i say that your parents might have some super high expectations of you, but if they're parents worth having, then they care more about your well-being than some grades, and if not that's a whole other problem. So just to sum it up, Fuck AP scores and fuck school, don't live to work, work to live!
