I think there are many good things about your profile.
I like your profile and portfolio.
I like you focus. You know what it is you do. You don't try to do everything. That's good.
Your profile overview need to be be expanded just a bit.
And get rid of this sentence, which begins your overview text:
"I am a college student."
Why did you include that? How is that supposed to help me?
Your Upwork profile is how you promote yourself as a professional freelancer who is offering services to clients.
It is not intended to be a biographical sketch.
I think it's quite good.
Preston is right, clients do not need to know the fact that you are a college student.
Also I think simply hide your below average test scores. Retake the tests on a later date and only display them when they are above average.
Plus, a little more info on what clients would get when hiring you would not hurt.
