Some people like to just drive up to a campus, park, walk around, and talk to a few students.
If they like the campus, they can plan a second visit for a formal guided tour and then schedule an interview in the admissions office. Sometimes, distance or time makes it difficult to schedule multiple visits. In those cases, you should call or e-mail the admissions office to see what times student tours and information sessions are offered. Although not all colleges require a personal interview, it's a good idea to request one if you believe that you are comfortable in the interview format and have noteworthy interpersonal skills. The guides detail what to look for on-campus, how to gather the information you need, the interview procedures, what you should expect, how you should conduct yourself and how to respond to the interviewer's questions.
