<human>: I'm currently taking Calculus in my Senior year of high school. I'm failing it completely. I take extra notes, always pay attention in class, gone for help after school with different math teachers, and have asked for help from my friends that understand it, and all tutoring has gotten me no further. I still don't get it and am still failing. My only options are to either drop the class into a much slower class (Which is supposedly "overcrowded" at the moment), or accept it and continue failing. All my other classes are high B's and A's, except this class, which I'm at a 41% in. What should I do?

Can you provide a brief overview of the text?
<bot>: Failing Calculus, all other grades good. Senior year, have gone for all types of help, don't understand if I should move down (If possible) or not.
