Transferring to UGA need 3 credits

Son wants to transfer to UGA he is currently a freshman at another Georgia College. He has a 3.6 but with his AP classes he will only have 27 credits by the April deadline for applications. Any suggestions on where he could pick up 3 more credits?

Take summer classes ( community college? )and apply in the fall for transfer in the spring?

"Transfer deadlines are for both the application and for all college transcripts. UGA will only review academic work that is completed and sent to our office by the deadline. For example, Fall transfer applicants have a deadline of 4/1, so we can only review work completed and into our office by 4/1. We cannot use work from a Spring term where classes are in progress and will be completed after the deadline. "
