Does the math ever get consistent? I ask this because I am in AP Calc right now and I get As on half the units and C-s on the other half. I can't for the life of me figure out what is changing. I've tried all the usual solutions like talking to my teacher and asking friends to explain it but half the math just doesn't click. If anyone knows what I'm talking about I would love to hear your thoughts, also does this mean I'm screwed for college calc? I may just be panicking because I'v been trained that only A's will do.

My offering is a TVR
