Chance me?

It seems like admissions is much more straightforward than in America. It’s literally just based on stats. That being said, I’m still nervous since a) I’m applying as an American and b) I’m applying to Arts and Sciences, which apparently is one of the more competitive faculties. Anyway, here are my stats:

SAT: 1570 (780 M/790 V)
SAT II: 800 Physics and Chem, 790 US, 730 Math II
GPA: 97/100 UW. Pretty sure that’s a 4.0. If course rigor matters, it’s high. 7 AP’s, 6 DE’s, the rest honors. Senior grades are good

Also, I applied Jan 15th (literally on the deadline). Can I expect a decision by April 1st, or will it be sometime later than that?
