In my high school, I don't think you could even take biology 101 without Latin. That all changed a few years later, too many genus apperatus, LOL.
What I mean is this. While the doctor who fixes you no doubt studied Latin; the mechanic or technician who fixes the doctor's car, scooter, bus, taxi, bicycle or whatever convenience, may not have. Does that make any of them more capable or ineligible to take a class? To say nothing about another thousand or so service industries.....
