Most colleges have gone to electronic files these days, which allows Admissions Offices to keep a pdf copy of past files. When you reapply to schools which rejected you, Admissions Directors can refer to your previous file. In your case, that may be good news, as I'm assuming your 2300 SAT is a huge improvement over your previous score.
That said, you might have better luck applying to a new group of schools because as JHS noted in another thread: Reapplying in ED after rejection last year.
"There are exceptions to everything, I guess, but I don't think I have ever heard of a student being successful reapplying to Harvard or Yale a year after being rejected or waitlisted there. The OP should probably accept that Yale is off the table and concentrate on other colleges (and other means of financing college).
Years ago, there was a famous thread on CC about "andisson", a top student who somehow managed to get rejected everywhere he applied, including what he thought was his safety school. He had a very productive gap year, and also did a great job analyzing what might have gone wrong with his original applications. He applied to a broader range of colleges the second time around, and received a number of admissions offers; he ultimately went to one of those colleges that goes by a single initial here on CC and has an admission rate to match.
But . . . not one single college of the colleges that had rejected him the year before accepted him when he reapplied. With his new-and-improved application and great gap year, he was accepted by almost all of the colleges to which he applied for the first time, and rejected by every college to which he reapplied.
So, reapply if you want, but don't give up any real opportunity to give your reapplication a better chance, because your reapplication probably has no chance no matter what you do."
