In high school, we all have this idea embedded into our minds on what is “cool" and what's not. But when every high school senior graduates and takes another step into the real world they soon realize that the “college cool" is a little different than their high school days.

Here's a list of common everyday things college kids do that high school students would cringe about.

1. Sleeping in public places

High School: “Quick take a picture! [insert name] is falling asleep in math class! Hilarious!"

College: “Same. I feel your pain bro."

2. Eating by yourself

High School: “What a loner. Poor kid has no friends, he's eating all alone."

College: “Finally time to relax. I have exactly 45 minutes to scarf down this sandwich before my next class."

3. Riding the bus

High School: “Can you please pick me up before school? The bus is so embarrassing and only the weird kids ride it."

College: “Dude. I'm a broke college student. I'm not buying a parking pass."

4. Actually studying

High School: “You actually studied for this test?! But it's so easy!"

College: “I have now lived at the library for two days straight."

5. “Scrubbing" to class

High School: “Wow look at her. She looks terrible. Must've been a rough morning."

College: (No comment because nobody cares what you look like in college.)

6. Admitting that you're broke

High School: “Like my new purse?! Thanks, it's Coach."

College: *Dumps out change at Taco Bell.* “Is this enough?"

7. Drinking no matter the day (or time)

High School: “Guys it's a Friday night and my parents are gone for the weekend. Ask your older brother to buy us alcohol and we'll have a huge party!"

College: “Margarita Mondays… Tequila Tuesdays… Wine Wednesdays…"

8. Sitting in the front of a class

High School: “He's such a nerd. He always sits in that seat as close as he can get to the board."

College: “100-person lecture hall? Score, there's a front seat open."

9. Going to tutoring

High School: “What a dork! She has to go to math tutoring after school. So embarrassing."

College: “Speech lab, math tutoring, research lab, writing center…sign me up please."

10. Failing a class

High School: “Oh my God did you hear about [insert name]? She failed biology this semester!"

College: “Hi, I'm [insert name] and this is the third time I'm taking this course…"

11. Not going to class

High School: “Dude [insert name] isn't at school today! I heard he's sick. He's going to be so behind tomorrow."

College: *Walk in on exam day.* “I've never seen these people before in my life."

Dear incoming college freshmen,

Welcome to the real world.
