My unweighted GPA is a 3.57. I understand that not much credence is given to class rank individually. But will being in the top 10% of my class give some context as to where my GPA puts me in the academic hierarchy and make my slightly above mediocre GPA look better? Any answers are greatly appreciated! Thanks in advance 
(BTW this is for more selective colleges, but I’m sure that is already assumed considering this is CC)
The short answer is: it depends. If a 3.57 and top 10% are from a school of the caliber of Exeter/Andover/TJHSST/Stuyvesant, perhaps. If it’s an underperforming school, no. Everything depends upon the context. If you have a 3.57 and superb SAT/ACT scores and AP scores, all the better.
Depends. If you have a 3.57 because your school is rigorous, then strong test scores (especially AP and SAT II) will help prove that.
