    When I took the first exam, I was 5 to find a 77, "C+", on my test paper. I went to Professor Jayne, who 6 my arguments but remained 7 I decided to try 8 although I didn't know what that 9 because schooling had always been easy for me.

A week later, I was surprised to find I had got a(n) "19". I hurried into Professor Jayne's office. He seemed to be expecting me.

    It was the 20 "A" on the course. The next year I received my scholarship. I've always remembered Professor Jayne's lesson: you alone must set your own standard of excellence.
