A little off the current topic but I have recently experienced the assessment day and the mental/verbal reasoning task is very time critical. You have 12 mins for 25 questions and I found this to be really tough. If anyone is sitting this test I would recommend bearing in mind that you only have 30 seconds per question so, if the question looks like it may require more than this time, put an asterix next to it and move on to the next in order to complete the shorter questions first. This probably sounds obvious but when you're there, it's easy to become fixated with a long question and fall well behind.
