ACT 32, should I keep studying for it?

I want to go to TOP 25 colleges. I’m a Chinese student who currently study in US high school

I improve 4 points from last time. So I’m not sure if I will improve more in April.

1: So should I prepare for ACT, and take it again in April. Or should I use this time to study for SAT II or learn a AP class on my own.
2: What is the chances that I get in top 25 colleges with ACT 32 and only 1 AP class currently?

Thank you guys!! Appreciate the helps :slight_smile:
