I'm sorry but I just can't resist this. I find your comment makes sense in that top schools tend to see the applicants' achievements and etc, but I do think your post is pretty harsh, especially the last part. I hope you realize that you are patronising the OP.Then that makes you much more interesting than the average applicant.
Play music? DUH. Your single is played in every radio station in South Africa, and within a few months, it's getting a lot of attention in Europe? AWESOME. You study college math and physics? DUH. You co-authored a paper with somebody at a local university? AWESOME.
You get the idea.
I saw you have posted several threads yourself asking for academic advise, and I don't think you might appreciate people talking down on you, using capslock and sarcasm to deliver a point.
