I am guessing that if my URM son had been in the OP’s HS, he would have felt like my son stole his place as he “only” had a 32 on his ACT and was ranked 16th. IMHO, if you are pulling all-nighters on a regular basis in HS, something is seriously wrong. I have a very clear memory of my son saying that he had to study for his AP Bio test and 30 minutes later he was back at the piano playing and singing While I can’t vouch for the difficulty or lack thereof of his class and HS tests, he did get a 5 on the AP Bio Test. What I am trying to point out with this example is that there are many students who are admitted to Ivy League schools who didn’t spend HS consistently burning the midnight oil studying. They had high grades with minimal effort and spent the rest of their time pursuing other things that interested them, including sometimes (gasp) going to parties, playing video games or just hanging out with friends. I think it was Hunt who said that it is a common misconception that all the kids admitted to the top-tier schools, worked really hard at academics in HS.
As of last week, I would have been able to say that my son, as a sophomore, still hadn’t pulled an all-nighter. However, during our last weekly Sunday phone call, he told me that his comp sci problem wasn’t cooperating last week and he had to start with a new solution at 2 a.m. and pulled his first all-nighter. According to him, once was enough! 
The idea that my son, or any other URM, stole a spot that belonged to someone else is absolutely ridiculous. Only 8% of my son’s class is AA, hence the moniker URM. Read Emenya’s post on the first page of this thread. His gratitude and positive spirit should be an example for all. Anyone who thinks that an unqualified URM stole his/her spot, should be required to read his post.
