Should you pull an all-nighter? Use this equation

We’ve all been there.

Somehow, through all the craziness of the quarter/semester/term, through the countless homework assignments, the tears and laughter, the events and study groups so carefully planned…

You realize you may have to stay up all night for school. As online math tutors, we’ve seen countless students log into the Yup app during a stressful all-nighter. Therefore, we’ve created a simple cost-benefit analysis formula that can help you decide whether or not to watch sunset and sunrise.

Before you decide to embark on this strange, twisted journey, plug in your own variables and see where the equation takes you:


The Variables


‘t’ is the time you have until the assignment is due or the test is administered. If judgment day is happening in under 24 hours, then you might think you already have no choice but to pull one. However, there are other variables to consider here.

When you plug into the equation:

t = 1 if you have greater than 24 hours to prepare.

t = -1 when you have less than 24 hours.


This is the likelihood that you’ll reach your target grade by winging the whole thing. How comfortable are you with the material?

This is also a self-expectation variable. Obviously you want to turn in only your best work, but you have to consider factors such as: what other classes must you be awake for the next morning? Do you want to look like a wilted piece of spinach? Can you afford to take a lower grade and preserve your sanity?

W = 5 if you could half-study/half-watch Netflix and be fine.

W = -5 if you still have to remove the plastic wrapping from the textbook.


F is for Focus. To what extent will you need to use cognitive function the next day? If you deprive yourself of sleep, you risk losing key bits of memory you worked all night to fortify. Even your ability to operate a motor vehicle becomes impaired.

If you have a test to perform well on, F = 1

If it’s an assignment you can crash on and not think about the next day, F = 5


This variable determines whether or not you should pull the All-Nighter.

If A is 0, sorry, but you probably should work through the night.

If A is below 0, consider hitting the books hard but getting enough rest to function and perform in the morning.

Mind you, these are simply suggestions. We understand students have busy lives, but we still recommend preparing far ahead of the 24-hour window. You can cut down on the time by heading to app store and downloading Yup, so you can chat with a professional tutor whenever you need homework help.
