Thanks - and to yours as well! I wasn’t able to DM you @Nat3755
Essentially ERC and Revelle were S24’s last ranked colleges because of the GE requirement of higher levels of HS Language Other Than English / proficiency test. S24 only took 3 years of Latin in HS. (Some other UC campuses and the other UCSD residential colleges indicate that 3 years of HS LOTE satisfy the GE requirement as described in further detail in this thread.)
This was on top of S24’s initial reaction to our tour, when he thought UCSD was just too big and he didn’t see himself fitting in there relative to the other campuses we had visited. (His reaction to the tour was really a surprise, because I had hoped it would be his top choice!)
Neither of these may be an issue for your S24… Wishing him and you best of luck!
