We're almost halfway through the semester, and you know what that means! Crippling exhaustion! In order to cram in a few moments of REM between note-taking, here are a few of the best tactics.

1.The Baseball Cap

A cap is a handy tool which can be used on sunny days. Most professors don’t care if you wear them in class, they’re discreet and stylish, and to the outside observer, it just looks like you’re looking down. Enjoy your snooze!

2.The Laptop Shield

Look at you being studious and taking notes on your laptop! Luckily, it also creates the perfect shield for your closed eyes and even helps to muffle snoring.

3.The Elbow Lean

We’ve all used this one. One elbow on your desk, resting your chin on your hand. I think this is the reason that professor’s suit jackets have elbow pads. You may wake up with a sore joint, but at least you remained upright during your nap. Less discreet, but decently comfortable.

4.The Blanket Nest

Best when used during the winter. I’m not sure why some professors keep the window open even when it’s below freezing, but it provides you with the perfect excuse to bring a cozy blanket to class. In order to fully envelope yourself in a warm cocoon, it’s helpful to brace your knees against your desk. From there, build up a blanket cushion on your shoulder and just tilt your head to the side a little bit. Sweet dreams!

5.The Dead Body

Just roll out of your desk onto the floor. Resign yourself to your fate. We all knew it was gonna happen eventually. Hopefully, you’ll wake up before class ends.

...There's also whatever this guy's doing.
