im so cooked bruh what do you mean Purdue rejected you with a 1500 SAT...

I'm so screwed 3.0 UW trying to go into engineering I can't even get into my state schools TAMU or Austin. I'm not dumb in the slightest, all I needed was for someone to tell me at 14 that my grades mattered beyond getting a diploma, and that college was WAY more competitive than I could imagine. How many other students like me is there? First gen, we know nothing about this process because our parents didn't go through it so all the info I have i got when I was already a senior and it was too late. Why am I being judged on my freshman grades that I got when i was FOURTEEN when I'll be going into college at eighteen?
