Say I finish high school with a “C” average, and my SAT is above 2200, and ACT is a 33. Will my test scores make up for my grades a lot?
No, it tells the colleges that you are a very bright but extremely lazy student.
No, you need to be at a 3.0 for most good schools and a 3.8+ for elites. Why is your GPA so low? If there’s a special circumstances then maybe there would be some leeway.
