My advice would have to be don't turn to the confuser until you've studied the books.
If you just keep doing the same questions over and over, you end up knowing the answer because it's answer B in the book, not because you actually know what you're being asked.
I used the confuser too much on Met, and failed 1st time. So, I just read through the textbooks again and again, a little and often. Then I re-took the exam without even looking at the confuser and got somewhere aroung 90%.
If you know someone who's also doing their PPL it's a great help to study together. I did Air Law on a flying scholarship scheme with about 10 people, so we all studied together. It made it a lot easier to take in.
Good luck with you exams, I found air law and met hardest, Nav and Comms easiest due to practical experience.
