Things I've Learnt at Uni

I've recently finished my first semester of university and it has been an entirely new experience for me. Here is what I've learnt:

-No-one (except your group members) cares if you do the work
-There is a 24 hour access building with couches and showers
-Nearly everything on campus is overpriced
-If you don't talk, people won't try to talk to you
-Get enough sleep, or fall asleep in lectures
-Going to lectures drunk is amusing but unproductive
-Avoid being at uni all day
-9am starts are brutal
-The Marxists will not leave you alone
-Clubs and societies aren't as fun as they sound, except for the drinking ones
-If you fail a subject, it just holds up your degree
-Textbooks are mostly useless and overpriced
-Unless you are phenomenal in your field, you are just one person in 40,000
-Arts students overdress, Science students underdress
-Residential students are another species, though friendly
-Tuesday night is the new uni night
-Rain is not conducive to a campus without covered walkways
-There is so much help out there if you know where to look

and lastly:

-Most people are there because they are intelligent. Use this to your advantage.
