Student Profile of Ivys?

If you have gotten into or are currently at an Ivy Leauge or another prestigious school…

Let us know your high school GPA, course load, ECs, standardized test scores (ACT/SAT), and anything else you believe helped you get to where you are today.

Now that you are in a good school, what advice do you have for current High School students? What would you have done differently to improve yourself?

MODERATOR’S NOTE:

This is all available on the results threads e.g.
http://talk.collegeconfidential.com/harvard-university/1962932-harvard-class-of-2021-regular-decision-results-only.html#latest

So any responding users should simply provide the link to his/her results.

Another source is each school’s Common Data Set, showing the stats of the last entering freshman class.
