Pat has hit the nail on the head with that. I dont know why people get bothered by the pass marks and what the answers to the personality tests are. Surely you should aim to get 100% in every test. Getting stressed about pass marks can only ever be detremental. If you knew the pass mark was 75% would you only strive to get 90%. Just do the tests to the best of your ability, dont worry the guy next to you is flying through them, and hope you have done enough.
