The first thing to know about college classes is they are so much better than high school classes. Every person around you is different, and for the most part, they are all new people you haven't ever met before. There are several types of people you'll meet in your classes throughout college, whether they're huge lectures with hundreds of people or smaller classes with 20 people.

The person you see everywhere and have no idea who they are:

When you first see this person, you won't think much of it. Then you see them in your next class, in the dining hall, and the library. Basically, everywhere you go, this person is there, but you have no idea who they are.

The person sleeping through the entire lecture:

You look over in class, and this person is lounged back, totally asleep. Every class, they show up just to sleep it out. Attendance isn't even collected, so why are you even showing up?

The person who only shows up for exams and the final:

For the most part, you sit by the same people and see the same people every class. Your huge lecture hall is only half filled for lectures. But then exam day hits, and the hall is jam-packed. People are stealing your unassigned seat and ready to take the test. How are you only showing up for the final?

The person who somehow knows the answer to every question:

For every question the professor asks, no matter how big or small, the same person is quick to throw their hand in the air with an answer. How do you know so much about a basic, introductory core class?

The person who shares their own experiences and asks too many questions:

There is always that one person who has to raise their hand and share there own long story to the class. Nobody cares about your own version of the professor's example. The same person will always be asking in-depth questions. They read too deep into things in front of 100 plus students who are trying to get through the long lecture.

The person who needs to eat a huge meal in the middle of class:

There will be that person who brings food to class. For the entire class, you'll be forced to hear them crunching their food, and also smelling their food. You'll be left disgusted or hungry yourself.

Then there is you, left asking yourself why you even rolled out of bed to come to this class. You should have just slept in, but instead, you're forced to interact with and be around all the people in your classes.
