Definitely get yourself a confuser, <a href="http://www.transair.co.uk" target="_blank">www.transair.co.uk</a> sell them, I believe for around 20 quid. I did my PPL from scratch in 3 weeks in the US, but I don't advise it, I really needed the time for school work, so I couldn't spend months doing it. Different exams take different lengths of revision time, law and rt you could probably pass after a few hours of reading and testing yourself (from the confuser), but exams like met and nav will take alot longer. The confuser really is a good book, however, don't rely on it solely, as it only teaches you the questions in the exams, not the information. Have a look round transair.co.uk for other books aswell, as you'll need other guides. And you get nuff respect off me for being able to motivate yourself, I only just managed being in a group of ten. Good luck, kebabman.
