Have you ever cheated during a school exam? Of course you have, no point in denying it.

All jokes aside, cheating is bad, and you’re about to teach one pupil a very important lesson by exposing his or her dirty tricks.

In the puzzle below, you will see four students. While none of them appears to be very interested in the exam, only one of them is cheating. Find out who in less than a minute to pass the test!

Have you spotted the naughty cheater yet? If not, let us help you analyze the details.

Student number 1 is clearly daydreaming. The paper in front of him is nearly blank and it looks like he doesn’t know what else to write down. Perhaps, he’s already done and is simply waiting for the teacher to let him leave the class!

Meanwhile, student number 4 looks very suspicious. His eyes look guilty and he appears to be reaching for something under the desk. Is he hiding a cheat sheet under there? Or perhaps he’s searching for the answers on his smartphone?

The truth is, we will never know, and without solid proof, we simply can’t accuse him of cheating!

This means that one of the two girls is cheating.

As you can see, student number 3 is playing with her long blonde hair. It looks like she already wrote her answers on the paper and has nothing better to do than wait for the bell to ring.

As for student number 2, she’s definitely cheating during this exam! How do we know this? Take a close look at her arms. She has formulas written all over them!
