Residual COA??

Hello! I’m a junior currently looking into colleges and because of financial circumstances, I’m looking mostly at those that offer a lot of academic scholarships. While searching, I have often come across the term Residual Cost of Attendance. I know residual means something that remains after other things are removed but I’m just confused because some schools offer “full ride” but then their Residual COA is like $13,000 ??
Thanks in advance!

That is not a full ride. That is full tuition. That would leave room and board (usually around $10K/year) and other fees and books.

Moving to the FA forum.
