u only need one more quarter of spanish, and when i looked on page 7 of the green booklet we got at orientation it says:
AP Spanish Lang - 5
clears the following GE courses: LTSP Lit 2A & 2B ; need one more course to complete GE sequence
AP Spanish Lit - 4
clears: LTSP 2A & 2B
taking Lit 2C would complete ur spanish GE's

i think that's LTSP 2C for the code.
