If you submit it any later than today, just think of all those kids who get a first crack at schools. Oh and if you thought aadsas took a while to process stuff in May and June, just imagine the headache of July and August when all the "late" apps roll in.
Get this, an 18 in May or June is worth about a 19 in August or September. Get your app in and give yourself a better chance in this crapshoot!
