Is there anything I can do to improve my chances?

ESSAY! If you’re applying early action, this is a good time to start on your Common Application statement and the two short answers.

I’m applying to UNC as well!

It will boil down to your essays and letters of recommendation. Good luck!

If you can get your ACT up to a 34, that will help. Otherwise, as @twogirls notes, make sure that you have killer essays.

The stats for UNC say a 33 ACT is well within range for acceptance. Sounds like your stats will be very competitive there
