...most colleges look at SAT and ACT scores, rather than your GPA. ...
WRONG.
...
When I myself went to college, they never once looked at my GPA in high school. ....
Yes they did.
No, they did not. I asked. Said I only needed a diploma. Which I had. I know this because my GPA was horrendous. I was a terrible student. I was worried that my exceptionally low GPA would keep me out of college. They didn't care. They said they didn't care. They wanted to know my SAT scores.
