From Winston S. Churchill's My Early Life, page 15 in the Folio Society edition.
I had scarcely passed my twelfth birthday when I entered the inhospitable regions of examinations, through which for the next seven years I was destined to journey. These examinations were a great trial to me. The subjects which were dearest to the examiners were almost invariably those I fancied least. I would have liked to have been examined in history, poetry and writing essays. The examiners, on the other hand, were partial to Latin and mathematics. And their will prevailed. Moreover, the questions which they asked on both these subjects were almost invariably those to which I was unable to suggest a satifactory answer. I should have liked to be asked to say what I knew. They always tried to ask what I did not know. When I would have willingly displayed my knowledge, they sought to expose my ignorance. This sort of treatment had only one result: I did not do well in examinations.
This was especially true of my entrance examination to Harrow. The Headmaster, Mr Welldon, however, took a broad-minded view of my Latin prose: he showed discernment in judging my general ability. This was the more remarkable, because I was found unable to answer a single question in the Latin paper. I wrote my name at the top of the page. I wrote down the number of the question '1'. After much reflection I put a bracket around it thus '(1)'. But thereafter I could not think of anything connected with it that was either relevant or true. Incidentally there arrived from nowhere in paticular a blot and several smudges. I gazed for two whole hours at this sad spectacle: and then merciful ushers collected my piece of foolscap with all the others and carried it up to the Headmaster's table. It was from these slender indications of scholarship that Mr Welldon drew the conclusion that I was worthy to pass into Harrow. It is very much to his credit. It showed that he was a man capable of looking beneath the surface of things: a man not dependent upon paper manifestations. I have always had the greatest regard for him.
