You don't have to be a student to get some good advice from one of the best film genres of all time: high school movies. Clueless [1]'s Cher Horowitz has plenty of wisdom to impart, and there's something to learn from every member of The Breakfast Club. Whether you're gearing up for a new semester or it's been years since you've picked up a mechanical pencil, you could certainly benefit from these 12 important lessons from Easy A, Heathers, and more great high school films.

Cleverly craft a classy look.

If there's one thing that Clueless taught me, it's that you should look as good up close as you do from across the classroom.

Be nice to everyone, because you never know who might grow up to be famous.

Even the guy with a bagel tucked in his pants (Sean "Spicoli" Penn) could win an Oscar some day.

Know that not everyone will be nice back.

There is a slim chance not everyone will want to be your friend, and that's OK. You don't want to be friends with that sexy sociopath anyway, trust me.

Don't stay inside and mope about it.

Unless you're supertight with your siblings à la The Virgin Suicides, in which case who needs friends? PLEASE LEAVE THE HOUSE.

Get out there! You might be surprised.

People really just want to get to know you, you sly wallflower, you.

Go talk to somebody new.

If you're anything like Superbad's Seth and Evan, you could get unexpected results leading to pimp-like feelings.

I mean, don't "talk" to too many new people.

You get what I mean by "talk," right? Unless, like Olive, you have a closet full of corsets and scarlet letters.

Don't let rumors get you down.

Just don't overreact Max Fischer style. Remain calm.

Turn to your friends for good advice.

Just be true to yourself and tell people how you really feel.

Unless you're talking to Zack Siler, the coolest kid in school, in which case keep it together, girl.

But don't go overboard.

You don't know these people that well yet, Crying Girl Who Doesn't Even Go to This School.

Because remember, you're actually pretty cool.

So put on your shades, dust your shoulders off, and flip up your collar (don't actually do that last part), and just be yourself. Hey, if Anthony Michael Hall can do it, so can you.
