^^Got me there Russ and shinny, thats true, and I understand the point now.
But still, so much luck to determine a person who is operating on someone else (although there would be some who got there purely/mostly on merit though)... It seems a bit risky, with so much luck involved for most applicants. Surely there is a better way to test the underlying skills, that involves less luck.
My idea for a replacement would be to eliminate the multiple choice factor, reduce the number of questions (whilst still maintaining time constraints) and make it all short answer (or mostly, as some patterns would be hard to draw I guess). Harder to guess, less luck, better/more deserved people getting their course and the underlying skills (that Russ and shinny mentioned) are still all there. More fair and better for the future.
