Help Should I drop AP Calc AB

I’ve always been at the highest math classes. I’m a junior currently and am two years ahead in math right now. I plan to take Ap stats and Ap comp Sci A next year for my math courses. Calc Ab has been very tough and the teacher isn’t helping out very much. The first two quarters I barely ended with a B. Right now I have a C- 70% and we only have two tests per quarter. Even if i manage to get a 100% on the next test I would still be barely at a 78%. We have weighted grades per section and tests are 60%. I plan to major in Biology and don’t know where I should drop it or not. My current schedule is
Ap chem
Ap Calc ab ( drop or not)
Gym class
Ap Lang
Elective class
Ap Euro
CIS French 4
I have all good grades in my other classes but Calc is really stressing me out, I put over 30 hours of studying into the last test to merely get a 73%. Should I stick with it or drop it altogether? Will colleges reject me if I drop the class? Please help asap since the quarter is almost done.

At a college doing holistic admission reading, a student two grades ahead in math dropping math may raise questions.

it depends on your target schools and the rest of your stats.

"Calc Ab has been very tough and the teacher isn’t helping out very much. "

What do you mean by that? Have you been working with that instructor consistently, and you still don’t understand the material?

Have you worked with the teacher consistently before or after school? utilized online resources such as Khan Academy? tried a tutor?

I have tried multiple different things, but the questions I’m missing are the units and simple multiplication stuff. The one’s I’m getting wrong are silly mistakes however they are so impactful that my grade is at a C right now.
