UHS has around 220-230.
When I started I thought it was a lot of people. After a year, it doesn't seem that big anymore just...hmm,normal. Gossip doesn't travel that fast, it usually takes two days from something to go from one end of the class to the other... And I must admit that I only know about half of my classmates by name. Additionally, because of the large size the class is very broken down into cliques. On the other hand, and this always made a positive impression on me, the professors know most of us by name and, at times, by reputation (good or bad, LOL).
