We've all done it. We sat through the never ending lectures, stayed up all hours of the night to write a paper we knew we would fail anyway, and we've laughed hysterically at the awful PowerPoint puns. Every semester we deal with new professors, each one with something new to offer. However, within the first day, we can already tell exactly what kind of professor they are...and whether or not we can sense the impending doom of the class.

1. The one that loves jokes.

No matter how bad they are, you feel obligated to fake laugh every time.

2. The attendance taker.

3. The crazy cat lady.

She loves talking about her cats, please don't get her started. I'm begging you. Run and hide from this one.

4. The one who just got out of grad school.

Come on man, half the people in this class are older than you.

5. "The final is cumulative."

I just. You know.

6. The low speaker.

I can already feel myself falling asleep.

7. The motivator.

Probably one of your favorite teachers. They're always happy to be there. This is the kind of teacher who loves teaching and it makes for a great learning environment.

You may not have run into all of these, but this is your warning: they're out there! No matter how weird or crazy our professors can be, there's nothing better than a professor who cares about their work and their students. A passion for teaching can go a long way, and those are the teachers we remember our whole lives.
