You raise an excellent point. A college's publications, particularly those intended to excite prospective students, are always carefully planned to show only the best and most attractive qualities of the school.
The real world of college and university life can be uncovered, though, if you're willing to do a little bold research. After you have taken the official tour and after you've read the brochures, you need to talk to some students and faculty. I know that, for some of you, asking unsolicited questions of people older than you is a daunting concept. Don't be afraid. Most students and faculty members are happy to give you their honest impressions of life at their school.
