Every major has its own distinct characteristics, whether it's in the sciences, in business, or even art. Here are a few things that define a biology major.

1. Most of your classes are either biology, chemistry, or math classes.

After all, why do you even need to learn anything else?

2. Half of your time is taken up by labs.

Biology, chemistry, anatomy — you get the point.

3. You have a love/hate relationship with lab classes.

Three hours for one class? How can someone even pay attention for that long?

4. You love your freshman biology classes because you know those classes will only get harder as you level up.

Junior and senior thesis classes will be the death of me.

5. You know how to calibrate a spectrophotometer by heart.

Zero it, put the blank in, then set it at 100 percent (words that would only make sense to a science major).

6. You realize that you took advantage of the easy worksheets for labs when you have to start turning in full lab reports.

What do you mean, I have to write everything from the abstract to the discussion?

7. The books for your major are always the most expensive ones.

Every other major has it easy. They have to pay maybe $200 for a few books. Biology majors can pay upwards of $300 for one.

8. You hate chemistry with a passion.

There's a reason you're a biology major, not a chemistry major.

9. You always get happy when you get out of a lab early.

Time for sleep before your next class.

10. You don't understand how people even find biology classes difficult.

Biology is hard? Have you ever tried taking a history course?

11. "In the hood" has a completely different meaning to you than it does to everyone else.

You mean in the fume hood, right?

12. You always feel like a mad scientist when you get to experiment with chemicals in lab classes.

How could you not feel like one when you're mixing agarose to perform electrophoresis?

13. There is always one specific subject you love learning about in class.

Genetics, parts of the cell, ATP production — we all have that one guilty pleasure.

14. You don't even want to begin to think about a minor.

Why would you want to add more classes to your already hectic schedule?

15. Your mental health is slowly declining.

It's okay to skip a class for your major every once in a while. Catch up on your sleep and stop stressing.

16. You never want to major in anything else, ever.

You have a love/hate relationship with your major and the classes that go along with it. But, you're passionate for the subject and never want to major in anything else.
