Do solid high school students ever take a fifth year in high school in order to improve their chances at top schools? In my example, I have a 4.0 GPA and 2280 SAT's, but I feel I could greatly improve my scores and ECs in this extra year of high school. Say I don't get admitted to Yale (my dream school), would I have a chance if I stayed in high school one more year?
In this year I would:
1) Greatly improve my SAT's to near perfect
2) Take many more AP classes (currently, I'm taking 6 and I took 3 last year). I would take 5 or 6 more in the extra year
3) Stand the possibility to be recruited for track as I see my times improving
4) Possibly start a nonprofit corporation dealing with energy conservation through delamping
I feel like I am just beginning to be prepared for schools like Harvard, Yale, Stanford, Williams, Pomona, and others. Would this be acceptable with them?
