Do now, in your state school, what you should have done in your high school those first three years. You will find “your people” on campus - they do exist, even if they are not the majority of your classmates. What you might not realize is that “your people” are would not be the majority of people on any campus. Maybe you haven’t met them yet, but there are students on campus who were at the top of their class - 4.0 and 1500+ SAT, who ended up there for a variety of reasons. Maybe they needed to stay near home because of a family situation, or maybe they were offered a scholarship they could afford to refuse. If your school has an honors program (most do), see what it takes to get into that, just because you didn’t qualify based on your HS record doesn’t mean you’re permanently shut out.
Think of it this way:
Your HS grades are not indicative of the work you can do.
So use this opportunity to do your best and show other colleges what you can do.
The Cheshire cat asked, “And who are you?.” At this point, your high schoo! GPA suggests that you are moderately prepared for the academic rigors of college. There are many students with superior credentials to yours who are eager to attend class, study, read and think. They have been marching down the road to greatness for a long time and under their own steam. Destiny isn’t the issue!
