I am ready to offer a B to anyone who would prefer not to take the test.”A number of students jumped up to thank the teacher and left the classroom. The teacher looked at the rest students and said. “Does anyone else want to get a B? This is your last chance.” Two more students decided to go. Seven students stayed. The teacher then handed out the papers. There were only three sentences on the paper: Congratulations! You have received an A in this class. Keep believing in yourself．I never had a teacher who gave a test like that, but I think that it is a test that any teacher could and should give. Students who do not have confidence in what they have learned are B students at most. The same is true for students in real life. The A students are those who believe in what they are doing because they have learned from both successes and failures. They have learned life’s lessons whether from school education or from events in their lives, and have become better people.
