Divide and conquer

Sometimes one person can’t study all the subjects that are about to be in the test. A practical method is to come to an agreement with your classmates that each of you will learn only one subject. That way, it would be easier to memorize it.

But how do you get the information to the rest of your friends? Well, that is easy. One way to transmit this information is having an agreed upon code – tap your fingers on the desk as if you were thinking but passing the answers to everyone else. Though we must clarify, this method only works with multiple-choice tests.
