Liam91 i just recently did my aptitude test and to be honest the maths section aside it seemed to me so long as you have an average understand of practical 'physics' (cogs, wiring a plug, basic electronic symbols, etc) and the english language, you should be fine, dont stop on a question though- in the first section i ran out of time *text deleted* i spent too long on a question (was only a 30 seconds too long but it cost me answering 2 questions) those nine mins fly by! you can always go back if you finish the section early.
