A survey like that will vary in its results depending on the time of year it's taken. And that was taken last spring. I think if you surveyed the freshman class during the first couple weeks of school they'd say everything is great, if you surveyed them now, they're not going to say that. There's a little tinkering every year. I'd say every year there's some modifications in the lottery system.
Seniors pick first.
And then after that, seniors get to live off-campus. Then we go through the lottery system, with seniors, juniors and sophomores. There's some unhappiness with the fact that each year you have to move. When you're assigned a place on campus as a first-year, maybe you can stay there for two years. There may be a nice community, a group of friends you're a part of, but at the end of an academic year, it's uprooted.
