Is it the possible the GC understood the opposite of what college adcomes said?
Because FL, like math, is sequential. You can’t skip a year - the loss during 14 months makes it nearly impossible to start again at the right speed/level. In the same way that you couldn’t take Algebra2, take a year off, do zero math of any kind, then expect to jump into precalculus without major trouble, you cannot take Latin 3 and wait a year then expect to jump into Latin 4.
What colleges generally want is level 3 (selective 4 year colleges) or level 4 or AP (highly selective colleges, roughly all within top 40 national universities&LACs). Continuous study is expected through level 3, 4, or AP.
(Level 2 is minimal for college entrance).
If a student discontinued Latin for a year, then jumped into Latin 4 “cold”, they’d likely have a very bad 1st quarter in the subject :(.
