It dosent really matter, Leads 65 has hit the nail on the head. On my last brush up, guys who were ofay with the subjetcs got hit hard when doing feedback questions.(especially those with no exposeure to the Qbank!!) Its not about the knowledge its about interpretation! Most of the questions are riddles to figure out. Its more like sitting reasoning tests than knowledge exmainations!
People knew the gen but couldnt handle the questioning style, thats where the Question bank is like pure gold!! Well done Alex and Bristol
