I just learned that I’m a USABO semifinalist. Most of my decisions will come out March 31 or early April. Is it too late if I do it within the next day or two? Also, should I do it by emailing the admissions office or some other way?
It couldn’t hurt to try. Send an email. I’m sure they will be excited for you.
The only people who know are the folks in Admissions at the particular schools you are applying. Give them a call.
