The teacher informs the class that they have a test on Monday. He tells them what they need to study and the sort of questions they will be asked.
Some of the class are sitting chatting to one another and don’t even hear the teacher talking.
Another bunch hear the teacher and plan to study at the weekend. But as soon as they leave the class it goes out their head.
Others hear the teacher, and also plan to study at the weekend. Saturday evening comes and they sit down to study but they get a text from a mate telling them about a party that’s happening that night. The books gets closed and they forget all about it.
The final group hear the teacher, plan to study and sit down saturday night to do so. They also hear about the party invite but plan their studying around it.
Monday comes along. Who passes the test?
