It's the week which is pretty much the most stressful in any student's life. A week where you have to cram a year's worth of studying into one long and painful all-nighter—an all-nighter full of red-eyed desperation and plenty of Adderall.
The only thing that can make you feel any better (apart from alcohol but that'll have to wait) is that you're not alone. Plenty of other students are enduring revision hell just like you. And with social media, you can share your torment and horror—and jokes, plenty of jokes to mask the pain—with the world.
Just like these people.
