I got a C in honors pre calc last semester and I had an idea that if I take the math 1 subject test and get an awesome score on it that colleges will be able to overlook the c. Would that be effective?
You should take the Math Level 2 since that is the precalc test. If you do well on it, then you can at least say that you know precalc. If you do well on it then you know a lot of precalc and your teacher may have been a harsh grader. If I were you, I’d take the test, because the alternative is for colleges to only see that you got a C in precalc, and you can change that right now.
Ok thank you 
I hope it will benefit my applications
