Just got back first SAT scores (pretty bad). Where do i go from here?

Basically your GPA doesn't count for anything because teachers give you a grade if you finish your work. Your SAT score indicates that you are just finishing the work, but not really understanding or thinking about your work. Let's be real. Getting into colleges like Berkeley is EXTREMELY competitive. You need to re-take the SAT or ACT and study for it. Work on your essays for entrance. When you get out of college you will be competing for jobs, so you had better get used to it.
