improve my grades

I don’t want to do this..
I NEED TO DO THIS

I’m a freshman in high school, and I have all AP classes, except math. My lowest grade is a C-, and it kills me every time I see it. There is a policy in my school where, if you are in an AP class, & have a C- or lower, you are subject to being kicked out of the class.

I CAN’T BE KICKED OUT.

Freshman year is really hard, I don’t know how I’m going to make it all the way to senior year.. unless my grades go up.
