@leachy114 -- As it happens, I've got a kid who's a freshman. Since she doesn't listen to me -- : ) -- I appreciate the opportunity. I'd offer two pieces of advice: 1) Try all kinds of new stuff. Don't get locked into thinking you have to do certain things. Take courses in subjects you've never heard of. Join groups that push you out of your comfort zone.
@leachy114: 2) The secret to college is relationships. Seriously. Curriculum and the formal stuff are useful only as mechanisms for forging to connections to others. So chat up people at the dining hall. Go to your prof's office hours. Etc.
