You alread knew school is cool, but it's even cooler when you don't have to get out of your PJs to go to class, especially when class is on a topic as awesome as interior design or bartending. That's the beauty of online classes, but we bet you didn't know you could take classes this cool—and each one for less than $20!

Novel Writing

Maybe you've been sitting on your idea for the next great American novel for years or maybe you've just always wanted to take a stab at it, but online novel-writing courses can help you get it done. You can choose from courses dedicated to things like plot and structure or finding your voice, or you can do an all-in-one workshop that walks you through it all. You can even get a little frisky with a course designed specifically to help you with your erotic novel, ooh-la-la!

Bartending

Who knew you didn't have to leave your home to become an ace bartender? Online bartending courses will walk you through the tools of the trade and (of course) proper mixology with classic recipes as well as the history of the various ingredients you'll be using. While it's a great way to refresh your skills if you're already bartending or to break into the field if you've always wanted to try, it's not just the pros who can benefit; plenty of at-home mixologists love it too!

Sign Language

You probably knew you could take Spanish or French classes, but did you know you can learn sign language just as easily? Aside from finally being able to talk with your mouth full, the skill can open doors for you and help you build relationships with the deaf community and maybe even make a few new friends!

We recommend our online American Sign Language course from International Open Academy ($9).

Makeup

Perfect the elegant swoop of a cat's eye and learn the ins and outs of highlighter without having to show your misteps along the way to anyone but the mirror. Online makeup classes can help you gain confidence if you're a newbie to makeup or help you prep for a special event.

Interior Design

An online interior design class might just be the thing you need to reinvigorate your space. Aside from getting some great inspiration, these courses dive into how to make a mood board, using the color wheel, and if you wanna go pro? They can even show you how to market yourself.
