Most of us probably cheated on our school exams at least once. After all, it was tempting at times. When a class was really hard or you struggled with the material, it seemed so much simpler to just take the easy way out.

And while academic honesty is good, it’s not hard to see why students cheat. In high school, many teens feel overwhelmed by the sheer amount of schoolwork. They also feel as though they don’t have the right resources to help them study in a way that’s beneficial to them. With a school day that starts at the crack of dawn and ends after extracurriculars and hours of homework, it’s easy to understand why some students cheat.

But there’s a bit of an art to cheating. You can’t just write all the answers down and get them all right, especially if you haven’t previously been doing well in the class. That’s a dead giveaway. You could always peek at your neighbor’s paper, but that’s obvious — and you run the risk of being noticed.

You have to come up with something more creative the teachers and other students won’t notice. These 45 cheaters did just that to ace their exams.
