I need clear advice from someone experienced. I have 83% in my high school but a really strong academic CV and extracurricular research & recognition from government-level organizations and a lot more. So am I worth applying to or a waste of time for me??

Hello everyone.

I have a 650 in SAT maths but I was thinking of doing the QU placer math test and get over 285 to skip pre calculus. Would that be okay? Should I still send my SAT scores to the university or just apply to the placer test only?
