This subject has been done to death , I would suggest you do a search . However whilst Im here . If you can get 98% from the confuser then youll pixx the exams . In MY Personal experience I found all the questions in my PPL exams to be in the confuser albeit with slightly different wording . If you can answer the questions in the confuse youll pass the exams . There is however no substitue for knowing the material and not just relying on the confuser
