BravoOne,
Take one subject at a time. PPL will take you a good couple of months to learn properly. Get a set of manuals like Pratt or Thom and read, read, read, revise and re-revise. Around, ooh, 2-3 hours per night, for 2 weeks per subject, should see you in a state where you're almost ready to take each exam. If you've got the "bug", then this should help stimulate your interest. Get a copy of the "PPL Confuser" too. This gives most of the questions on the exam paper and in-detail explanations on the answer.
Remember, reading the question is half of the answer. With PPL exams, this particularly pertinent. An element of the exam is understanding the poor wording of the questions.
Yours etc.
