Right before the test.

It's one minute before catastrophe. You tell to you: " I'm ready for that". Well, its just motivation. Maybe it's not the truth. You're taking out your script to throw a last look in. The teacher comes in and requests the class to put the scripts and books away. There's just one problem. You wanted to check something on the next page. It's just one look!!

Check it.

Put the script away
