I’ve been off the site for a while, but info might be useful to others. My S earned A LOT of AP & IB credit. BUT, for Bio, they would only give him credit for the one semester course for non-Bio majors. He ended up taking the full year Bio course & acing both semesters (he felt the High Level IB Bio course he took in high school was a better course). For Freshman Chemistry, he was able to take the Honors college version. That class had no more than thirty (30) students in it! And as someone else already pointed out, the higher the class # (200s, 300s, 400s), the class size usually decreases.
