College is a different experience for everyone, but there are some mistakes just about everyone makes sometime before senior year. No matter what school you go to, no matter what crowd you're in, greek life or not, you are sure to make a few rookie mistakes before you graduate and go out into the world of adulting.

1. Missing an important exam. Whether you forgot about an online test or get a little too drunk the night before and sleep through your 8 a.m. test.

2. Taking an 8 a.m. 8 a.m.'s are always a mistake because there is literally always something going on the night before to distract you from getting to bed on time.

3. Not making an advising appointment. And subsequently not getting to register for classes on time.

4. Not taking a class in a crucial semester. And almost not graduating on time because of it.

5. Not preparing for a snow day. Living on campus may seem like you are set with the dining hall, but being stuck in a dorm for several days requires one key thing campus doesn't sell: alcohol.

6. Not buying a book for class. You can only BS for so long before the first test where you realize that half the answers were never said in class.

7. Fighting with a roommate. Whether you felt you were missing some cereal or something more serious happens, you always regret fighting with a close friend.

8. Dropping a class you need because you want to put it off. You won't like it any more next semester.

9. Missing the add/drop date or the W date. Now you have to either suffer through or take the L.

10. Having a fake ID. Those things never make it to your 21st and then there's always those awkward few months that you can't go out anymore.

11. Getting tickets on campus. There is always a way the parking people will get you.

12. Losing things moving. Whether it's dorm to home, apartment to apartment, or any other move, you are sure to lose something important.

13. Not packing pajamas when you stay over at a friend's house. No matter if you were being scandalous or just having a night out with friends, people will judge you the next day still in your clothes from the night before.

14. Not buying a planner. Try keeping up with what's due in 18 credit hours without one.

15. Wasting time hanging out with people you don't like. This isn't high school anymore, it's OK to choose friends off who you actually like (not who's mom is friends with your mom) without feeling guilty about stepping on toes.

College is a stressful time, but at least you know you're doing OK once you make it to senior year. No matter how many of these mistakes you've made.
