Ohhh, okay, that makes more sense.
There’s a February 8th test date for the ACT (unlike the SAT which has no January or February test date). You’d have two months to prep, and it would be scored in time for fall transfer apps. That seems to me like that would be an appropriate timeline, and it seems likely that you could post an impressive score if you were disciplined about preparing. That could be a help with the reachier schools you’re considering.
