To those of you that are celebrating the OP's rejection, know this: having a lower GPA and a lower MCAT score does not mean that you a more well-rounded, diverse candidate. It means that you are not as smart, and didn't work as hard.
I see the point you are trying to make towelie, but why demean others by saying that low MCAT and GPA= being "not as smart" and "not working hard."? although that is true the majority of the time, it is an assertion that can be proven false and can offend people.
Definition of arrogance according to MSN Encarta dictionary:
arrogance: proudly contemptuous, feeling or showing self-importance and contempt or disregard for others.
By your statement you are disregarding/showing contempt for people with lower GPAs and MCATs.
Keep in mind that not everyone enters college knowing they want to do medicine. Unless you plan on graduate school, there is hardly any incentive to keep high grades and master every class.. People with scores/GPA that high probably knew they wanted to be a doctor from day one, and did an excellent job of using their talent to achieve, as the OP did with his tremendous GPA and MCAT. However I still think it is silly to say the OP is entitled to an interview based on his scores and GPA, or even his ECs. Schools can choose people based on whatever minute criteria they feel like, and none of us can do anything about it. There are still LOR's, PS, the language/writing he used to enter his ECs, secondaries, etc. and you are assuming that given this guy's GPA/scores that everything else is stellar. However there is no way of proving that, once again it is an assertion that can be proven wrong many times.
Towelie, I'll bet that you have amazing scores/GPA/EC's/PS because you seem to be defending the "overachieving" type students, and you've had 15 interviews which is a testament to how strong your app is. I've met many people with stats like the OP that are the most articulate, warm, humble people I know. And they did awesome in the med school application process. But many of them got rejections too. Its part of the game, especially for schools as selective as UCSF... if may be merely an acknowledgement of how strong the applicant pool is this year rather than any of the OP's shortcomings. There could be Olympic medalists, newspaper writers, entrepreneurs, people who unique life experiences, etc. that also have good #"s, and maybe UCSF wants a class with a diverse array of experiences. Nobody is "applauding" this guy's rejection. We're merely trying to tell him that there are no guarantees in this process, no matter what your stats, scores, ECs, etc. You seem to have a chip on your shoulder in regards to people making generalizations about "over-achieving" students, yet you are fighting back by making generalizations about those with lower GPA/MCATs, basically doing the exact same thing. I understand your position and it must be tough when people judge what kind of person you are from your GPA and MCAT. It would probably be more effective, however, to make people aware of their stereotypes rather than perpetuating more of them. Just my .02
