Unfortunately just about all of the ones that are university-based or four year programs are. Most are finishing up auditions over the next few weeks, so their slots are full. While others aren't even accepting any applications anymore and haven't been for quite a while now.
I suggest looking at two year schools (they have auditions and accept applications year-round) or looking at other schools you're interested in for when their deadlines are. I would focus on the latter first since it's so late in the application year.
I feel like UCF has a rolling admissions process. I'm not sure if that is the same with their MT program. I would look into it, though. Also, I'm not sure how conservatory-style their training is.
Also keep in mind that some schools that have rolling admissions with application deadlines in April have been slowly creating their class as the year has gone on. So there are less avaliable class spots now which means you're gonna have less of a chance of getting an acceptance at this stage of the game. Not all schools do this however, but I know for a fact that UArts is one that does. Just something to keep in mind.
