For high school? It depended on the class I think, but I'm going to estimate about 20. My AP Calc class had 8 people in it. In total, I had about 156 in my graduating class. That's actually considered big in my school's area. The other all-girls private school down the block had 60 people in their graduating class the same year.

Oh, and I apologize, this is actually my other LiveJournal account. I have 2.

it's alright. do you know how many ppl are usually in one typical class in public schools in your country. because where i come from 23-30 is normal number of pupils in a public school ...
