Just a word of caution re: summer programs. TASP & a few others are genuinely competitive and well-regarded, but many summer programs are only notionally ‘competitive’ - the ability to pay is the key variable. TASP could impress; others not so much.
But for all of them, the only way to turn them into an admissions asset is for the student to demonstrate what they have done with the experience: ‘had X life changing experience, have already built on that change by doing Y, and am now working towards Z’. This is not my opinion, but explicit advice an admissions dean at Princeton gave a group of students.
