Pre-med. These two syllables are enough to make any parent proud and any college student cry. Being pre-med means endless science classes and minimal free-time. Unless you actually are a pre-med student, you might never understand the struggle. If you ever see one of us slaving away in the library or dragging our sorry butts to another lab and wonder what the heck is actually going on, here's some times "Grey's Anatomy" explained what it's like to be us perfectly.

1. Always tired. ALWAYS.

2. What happens when you're going crazy from staring at chemical equations and anatomy terms and you just need a break

3. When your professor assigns a problem you don't understand at all

4. When you get a decent score on an orgo exam

5. When you've been up for about 24 hours and you just want to sleep but you can't stop thinking about all the work you have to do

6. Your professor when you try and sound smart in front of the class

7. When you tell your mom how hard it is and she shuts you down

8. Trying to convince yourself you're not going to fail an exam even though you studied all night

9. When someone who understands organic chemistry is trying to teach it to you

10. After five nights straight of being at the library until 3 a.m. and people ask how you're doing

11. When you're over not having a social life and decide to go out once

12. When your friends who aren't pre-med complain about stuff

13. "Pop quiz on the chapter from last night!"

14. "What are you gonna do after graduation?"

15. Pretty much every time online homework is involved
