The class sizes can vary wildly due to scheduling needs. I’ve had years where one class period was 24 and the next was 38, and no one seemed able to do anything about it. But yes, L.A. ... Like this year, I have six classes (we’re on an 8 block schedule, which I hate) and my class sizes are between 27 and 36. It’s the science teachers who really get slammed, for some reason. Ours had over 40 in every class last year. It’s just nuts.
