How much knowledge does a child need to have in order to pass an Eleven Plus examination?
There is no straight forward answer. Perhaps Sissa ben Dahir could have come close to answering the question. You will, no doubt, recall that he was offered a reward for inventing the game of chess. He asked a grain of wheat to be placed on the first square, two grains on the second square, four grains on the third square and eight grains on the fourth square. He wanted enough wheat to be able to cover all 64 squares on the chess board.
The King asked him why he has coveted so little.
Sissa ben Dahir explained that he had asked for more wheat than was in the whole kingdom. He had asked for two to the power of sixty four grains of wheat! This was 43,252,003,274,489,856,000 grains of wheat!
Eleven Plus parents simply have to start at the beginning and add grains of knowledge one square at a time. A little bit one day, a bit more the next and let the knowledge build and build.
