Only use the 'PPL Confuser' to help with exam revision - not for learning the subject matter. Don't be told otherwise by lazy gits who think that the book is the be all and end all! If you think that you will pass by 'mugging up the answers' - you will probably fail the 'Oral questions' part of the Skill Test as that requires a good general level of knowledge, not the ability to reproduce memorized answers.
