1. The first week is crucial for your social life.

It's perfectly fine to sit down in the cafeteria with complete strangers during the first week, but after that, it's a bit shady.

2. Picking classes feels like wrestling with Satan.

Pick your battles and spare your mornings.

3. Yes, you will get homework the very first day.

And, YES, that homework is indeed 30 pages long.

4. Befriending your RAs should be a top priority.

'Cause let's be honest, a little familiarity with the authorities goes a long way when there are drunken 18-year-olds turning your dorm room into a strip club.

5. Cliques still exist...

6. ...and they still need to be avoided.

Emotional detachment is key if you feel like you're being sucked into a clique.

7. Some messages are better left unanswered.

Let's not condone bad texting manners.

8. You will probably be sick 50 percent of the time.

After 30 cough drops, seven cups of tea and all the painkillers in the world, you will still have no idea why you keep getting sick. Not. A. Clue.

9. Invitations are overrated.

An invitation isn't going to help if one of the fraternity brothers hates you or you forgot to buy a ticket. Just cross your fingers and show up.

10. Group chats are life.

They contain your dinner plans, your inside jokes, the latest gossip and your friends' whereabouts, all in one stream of texts.

11. There are more people with commitment issues in college than alcoholics in an AA meeting.

But there are also lots of alcoholics in college. So there's that.

12. The U.S. reaaaally doesn't like alcohol and drug use.

'Nuff said.

13. People talk about their hookups way too much.

...Which can be tricky in a small school where everyone knows everyone.

14. The common fridge is NOT a safe space.

People are animals when it comes to common fridges, so expect to find your food gone or even vandalized. Buying your own mini-fridge is always a good idea.

15. You will meet amazing people.

Because everyone a lot of people in college are easy-going.

16. The Freshman 15 is not a myth.

Late-night snacks, impromptu cafeteria runs and non-perishable snacks will get to you in the end.

17. Roommate feuds require blankets.

Yes, you read that right. Why fight with your roommate over the thermostat when you can just change your blanket for a lighter or heavier one? Problem solved.

18. People take finals way too seriously.

The library will be jam-packed during finals and you will wonder if you should also be freaking out. Or maybe you're one of those people who's already freaking out.

19. Pre-med kids end up with 8 a.m. classes.

Sorry to break it to you. (It's how they eliminate the weak ones from the pre-med track.)

20. If you keep an open mind, it will be the time of your life.
