My GPA is Low

I am a sophomore in highschool and have a 2.9 gpa from Freshman Year.
I take all accelerated classes and have Taken AP Calculus My freshman year of highschool.
I am taking AP Human Geo and Stats this year with other accelaterd classes.
My School goes on a quarter grading system not semester and i dont know how to raise my gpa.
I am really nervous that i wont get accepted into college. What is the highest Gpa i could atain my Senior Year.

Really? You haven’t figured out that better grades (better studying) in sophomore year will raise your grades?

Probably a 4.0 UW.

You’re probably noticing a lack of empathy on my part to your great distress. You are a sophomore. If you want to attend a competitive college you know what to do. Just do it.

yeah just need to devote more time to study and get good grades. no other way really

Sit down and study. You have three more quarters to redeem yourself.
