There are some LACs still taking apps (even though their deadlines on their websites might have passed.) There are also plenty of larger unis still taking apps too.
At some point towards the end of April, NACAC will publish a list of schools still taking apps for the Fall. That’s usually several hundred schools…all the schools that will be on that list are taking apps right now.
You might not prefer any schools on those lists though to the ones where you already have been accepted.
