1. The one who sits in the front row

2. The one who is always online shopping

It doesn't matter whether it's fall, winter, spring or summer - these people are online shopping every single lecture. They usually sit a row or few in front of you, and while the professor is lecturing, instead of taking notes or even trying to act like they're listening, they just aimlessly scroll through Aritzia, Forever 21 and Zara. The only time their eyes ever leave their computer screen is when class ends, so they're basically just there for giggles.

3. The one who always falls asleep

This person comes to class every day, but somehow never stays awake for more than 20 minutes. You can sometimes hear the occasional snore from a corner of a large lecture hall, or catch their heads nodding like a pendulum near the front of the class if they're the studious type. But let's be real here: we've all been one of those students at some point.

4. The one who never pays attention

This category of students is probably the most common. Sure, they'll go to class, but all they do is surf through memes on Facebook or watch others play Fortnite. These people are in class for the attendance grade, not to learn. On occasion, they may raise their hand in class to ask a generic, vague question that has already been covered but hey, gotta get that participation grade. They're just doing everything they can to survive college, and honestly, it's a mood.

5. The one who never studies (but still aces the class)

Standing as probably the most frustrating category of people in this list, these students won't know about a midterm until two days before. The day before the exam, they'll be chilling in Malibu and partying at night. They go to class every once in a while when the class time doesn't clash with one of their many elaborate social plans, but never pay attention. Somehow, they still ace all their exams and end up with the top grade in the class.

6. The one who is always stressed

These people will start studying for a midterm at least two weeks before hand, and will be so stressed about homework and classes that they spend more time worrying about the workload than actually doing the work itself. They're in desperate need of a relaxing vacation that they're too stressed to plan, and they disappear from the outside world for weeks at a time. You can usually find them in a study room in a library, where they probably have been in for the past week.

7. The one you've never seen before

You didn't even know that they were in your class to begin with because they never show up until it's exam week. Are they too smart for the class or struggling too hard to care? The world may never know. Maybe they're just straight chilling in their apartments being lazy, but most of time, they probably didn't even put this class on their schedules. Catch them going to Disneyland on a weekday at least once a month, which is more than the frequency that they attend class.
