The assessment day starts with you taking 6 different tests. A verbal reasoning, logic and 4 maths based tests. You have to achieve 40% overall to proceed onto the next stage, which is a presentation and an interview. The maths test aren't difficult if you've practiced them. They involve mostly logic and riddle type questions. And it's a non-calculator paper. It would DEFINITELY help to brush up on your geometry (trig) and arithmetic. I didn't make the mark and was asked to leave after the tests although I feel if I did these tests 4 years ago, I would have passed. I do think these tests should be done online. Seems a waste of time travelling all the way there only to be rejected after doing the tests. Around 1/3 of the candidates on the day failed the tests.
