When the acoustic version of lollipop by Lil Wayne comes on your Pandora study station at 2 a.m. while you're outlining your bio textbook, you know your classes might be to blame. Sometimes, it feels like friends and family really don't understand what it takes to do well in your classes, or what you're going through. Whether it's biology, chemistry, biomedical engineering, nursing, or some other scientific field of study, we're all feeling the same pains.

1. Reading.

Endless textbook chapters to read and outline, definitely enough to gain some respect from English majors.

2. Autocorrect.

Having autocorrect tell you some of the terms you have to know or understand aren't recognized as a real words. Yes -- thank you, Apple, for your help.

3. Friendship.

There's no room for FOMO. You have to create a good balance between hanging out and working, hoping your friends understand you have less free time than them and can't always be around. It's awful missing out on fun because of the work you have to get done.

4. Strange Interests.

Wondering why you actually find learning everything there is to know about bacteria interesting and being excited to move onto eukaryotes.

5. Sleep Deprivation.

I'm busy staying up, wishing there was a few more hours in the day, while becoming more and more tired and slap happy. Daydreaming about my bed while crawling to class. At least I caught up on some sleep over the weekend and my face stopped twitching.

6. Wanting to go out.

Knowing you have a lot of work to do over the weekend and making the choice between going out and staying in.

7. Big classes.

Lectures are huge at most schools, making you feel insignificant. This makes it harder to get to know your teachers and classmates, but not impossible. With some work you form study groups and make it to office hours.

8. Big difference from high school classes.

Sitting in class and wondering where this was covered when you took the same subject in high school. It's like that whole year of high school is combined into a couple months of a college classes.

9. Foreign professors.

It seems like most professors with English as their second language work in science and math departments.

10. Horrible eating habits.

Basically, you eat when you can. Sometimes I lose track of time and don't eat dinner until midnight and it's usually something easy to make. It's a wonder I don't have scurvy due to lack of vitamins.

11. The Holy Trinity.

Tutoring sessions, extra help, and office hours.

12. Coffee.

Nothing is OK until I get some coffee, then I can start my day.

13. Wondering why.

Why not just switch majors and make life easier? The science, the challenge, the weird facts, and the accomplishments are all rewards of the struggle. You know you'll never actually switch out of these classes regardless of how stressed you are. Just take a quick nap and you'll be ready to go learn.
