Do some homework on the college before you visit. Know about majors and programs ahead of time, and take a list of questions with you to have answered. You don't have to ask all the questions--many will be asked for you or answered in the info session. Pay attention, take notes. Look around. Listen. And after the visit, hang out in the coffee shop for as long as it takes you to have a mocha-something and write down what you saw, heard, felt, and smelled that day. Believe it or not, later these notes will trigger memories to help you keep all your college visits clear. Another thing--don't make any decision about applying to the college based on your tour guide. Chances are you won't hang out with him or her, have classes together, or even share anything in common. Trust your own instincts--not those of someone else.
