It seems like questions just get to me and I become curious and even frustrated because I do not know the answers.
So here are some questions I have been having and I would really qppreciate it if you guys could answer them and explain thoroughly.

1. I had a B in P.E. my first semester in high school, it was my first B ever. I am concerned about how much it affects me, my GPA in particular, because I really want to go to Johns Hopkins or Stanford, which are pretty competitive schools.

2. Which GPA do the colleges look at? The weighted or the cumulative?

3. Also about GPA, I have 4.0 weighted GPA and 3.28 cumulative, and I was wondering what are my chances of bring that up to 4.68 by my senior year? I am a freshman this year and I plan to take up to 10 AP classes and I am willing to work, except I do not know how hard they are though.

4. Should I take the SAT or the ACT, does one stand out more than the other? What should I know about them?

Thank you.
