<p>jacob624: Bedtimes vary. Personally myself and the group I worked with would go to bed fairly late (after midnight always, sometimes until 2 or 3). We were among the dumber ones so the problem sets took more time but it was not uncommon for most to be fairly sleep deprived. I don’t think many people went to bed before 11.</p>
<p>There are a lot of Koreans. Last year there were probably around ten out of the eighty or so.</p>
