Oh, just thought of something else. If you do decide to ignore my advice and study for the PPL theory exams highschool-style, with the aim of getting the minimum passing grade with minimum effort, think again.
Your PPL skills test (the final flight test) will include an oral exam which may cover literally everything that was covered in the theory exams and the examiner can and will fail you on that part of the exam. Even if your preparation, flying, R/T, nav and everything is completely by the book.
Examiners are really good at spotting those who learned PPL theory by means of the confuser alone.
