HELP: Failing AP Calc BC
School's just started but I've already taken 3 tests in my school's BC course and failed every single one of them despite studying immensely, landing me a C in my grade right now. I've never struggled with math so much as this, so I'm really shocked and disappointed at myself, yet I don't know what's going on and how to improve. Maybe it's just the Collegeboard question format, but I study with a lot of their practice questions my teacher gives me, and I still do poorly.
If you guys have taken this course before, can you give me some advice, practice material, Youtubers, wtv helped you? I'm really worried since I know this course will only get harder as time progresses, and I genuinely don't know how to go from here, I feel hella lost. Any help is very very appreciated! Thank you all <3
