Yep, good advice PFO. The PPL Confuser is the book to have, buy it, but dont worry about it for a while. Get the Trevor Thom or Jeremy Pratt books as well as you will need them sooner rather than later. Once you have started your PPL hammer your Air Law books as you cant fly solo till youve passed the exam. Your ppl Confuser will help loads, as it will later with all your other exams.
Good luck and kind regards.
