1. Splurge on food

This is where you look busy by putting aside your self-esteem and having a nice meal by yourself either in the food court, or a bathroom stall...

2. Try and socialize

If you had a fun group of friends then finding ways to kill time wouldn't be much of an issue

3. Walk around aimlessly

Maybe this would be a good opportunity to take a hike around campus and try and enjoy the views, despite all the stairs.

4. Sit and have a drink or two

If you really can't find anyone to kill time with, then turn to looking busy with a drink of anything you can find (water, coffee, a beer or two...)

5. Study

I guess you could head down to the campus library and catch up on some work... Only if you're really desperate.
