Hi SB,
A good set of books is what you need, plus the PPL confuser. The AFE Q & A simplifier is also a good help.
I did ground school for nearly all the subjects and got my Air Law done. I can honestly say it was helpful at the time but I couldn't remember much of it when I finished and when it came to winter time when I was doing my exams.
In the end I read each book cover to cover, went through the CBTs and then trained on the confuser to make sure I understood and passed the exams.
The thing is, that some parts of the modules will be more understandable once you've actually flown and performed the exercise. For instance, Navigation. It's not until you actually use whizz wheels, VORs and fill in plogs that you'll be more comfortable with doing the exam.
Anyone with even a half decent memory will be able to pass the exams (my attention span is quite short), but the confuser helps massively and trains the answers into you.
Good luck, it's a massively rewarding and enjoyable experience
