First of all, u don't have to meet any requirements other than the income <60K.
I don't know exactly how weighted gpa works, as my school only did unweighted, but here were my senior year (last year) and I was selected as a finalist:
Cumulative gpa: 3.8
Class rank: 12/97
Jr and Sr year Classes: 5 AP total, rest were honors except for a couple
Community service: helped start community service project that got state and international awards. Roughly 400 hours of service
Extracurriculars: nhs, academic team, future problem solving team, community problem solving team, varsity tennis team, class officer
So although I did not have the best test scores compared to other candidates, I was still selected as a finalist. That being said, I had an ass-ton of community service, extracurriculars, and leadership positions...so those probably carried me. But writing a good essay and having good teacher rec letters help A LOT, and i'm sure those contributed as well. I poured my heart and soul into the main essay, almost to the point where it pained me to read it and I didn't want anybody else to read it.
I really was not expecting to be a finalist bc, like you, I was really concerned with my scores and gpa. Just remember those don't mean everything. Sadly though, I wasn't picked as a college match and I didn't get picked reg decision. BUT I do currently have a full ride at my current school, a school i'm happy with.
If u have any more questions, feel free to message me!
