  1. Help!
  2. Also, if you hate a school on first sight, ditch. Go eat at a diner or visit another college nearby.

  3. Attend classes. Meet with professors. Ask questions you actually want the answers to, not questions you think will impress them.

  4. Look at the event flyers
    Borrowed from my mom. See what people are advertising and talking about on campus. Is it social justice, art, debate, comedy, music, all of it?

  5. Don't worry about what they think of you. None of these people is going to be in charge of your admission. Keep your eyes wide open. Look at other students. Do they look like people you could be friends with?

  6. Do an overnight!
    I remember that some of the smaller liberal arts colleges will let you spend the night with a student. I assume they still do that. Fun fact: I thought I was gonna go to this school in Oregon, but I spent the night and hated it. AND THAT IS OKAY, TOO. (Just another school to cross off the list)

  7. Try the cafeteria if you can
    They won't be trying to impress you and it'll help ground you in the day-to-day mindset of the college

  8. Hang out in the student center or the on-campus coffee place for 30 minutes and people watch.
    It'll give you a good vibe on the student life.

  9. Check out the WiFi situation
    I didn't even think about this when I was applying/touring schools but the wifi here is terrible and has a huge negative impact on my life

  10. Kick the tires on the dining halls
    It's pretty rare for campus food to move past 'decent,' but there's a world of difference between 'decent' and 'mediocre' over 4 years

  11. Note whether fraternities/sororities are a big presence on the campus or not and consider whether that's something you want in a college - if it's a large percentage of the college it will have a significant impact on you whether or not you join just by dominating campus culture

  12. Ask about financial aid; how many people are on it, whether there's a sense of impending crushing debt, etc. Even if you don't need any of it yourself, you'll often find better, more committed students at a place that gives good financial aid. (From a professor's perspective, at least.)
