From OP’s GA Tech blog article. This is his argument for why no one knows who will get in.
“Nearly 600 of our denied students had either a 35-36 ACT or 1500-1600 SAT (CR+M). The vast majority of students who were denied or deferred have taken AP Calculus or higher and are in the top 10% of their class and taking the toughest curriculum in that context. In other words, numbers are by no means the whole story.”
True, but you can make educated guesses and do a lot better than chance.
For example, he talks about rejecting 35 and 36 ACT scorers. I bet that with that score, if you are in the top 5% of your class and not an ORM, you are very likely to get in. Of the 600 they rejected, how many do you think are Top 5% and not ORM? I bet not very many.
