Sophomore year you'll be in the new auditorium which just opened this year. It's really big with comfy chairs that are on wheels. I'm not sure if you'll be in Shands next year which is across the street (we were there first semester). If so that classroom is normal lecture hall style with chairs attached to those long bench desks. They're quite comfortable. If you're in Lecture Hall A which is what we're in now it's also lecture hall style, the seats are a bit less comfortable but still fine for 4 hours of lecture. If they want to put you guys in there they'll be making some changes this summer to put in more desks. If not, you'll be in Shands which isn't a big deal. In fact, we're the first freshmen class to be in Lecture Hall A. All before have been in Shands. Positives about Shands is that there are lots of choices for buying food when you didn't bring lunch. At the vet school your only choices to buy lunch are from the bookstore or from Einstein's.
Don't worry about the overcrowding situation. They'll have somewhere for you guys to go in August.
