Tips for Supplemental Essays? Chance?

Hey, CC.
I know for USC its a bit late for actually submitting the application, but I would greatly appreciate some help. Im at Starbucks writing it as we speak.

Is there I should look out for or try to emphasize? I know they love diversity, and involvement in one’s community, but I feel that the supplementary essays are so broad and different. Idk, im having trouble.

If i could send someone a sample, could you proofread? that would be awesome.

That said, could someone chance me?

applying RD for class of 2020 as an Electrical Engineer
GPA: 4.26 (all A’s and A+'s in math and science classes)
ACT: 33
SAT: 2150
Subject: Math 800, Physics 710-800

Lots of leadership positions, extracurriculars, awards for service.
maybe 800-1000 hours total. Some have lasted since freshman year.

NO STEM RELATED EC’s

My weakest point is the essays. Dont get me wrong, I write good essays, but they take a loooooooong time. My UC one took about a month to complete.

But if I could start on the right track, I can really do these 4 supplementary essays.

THANKS!!!
