I found the Gliems PPL Reviewer a worthwhile read when preparing for the actual exam.
The Jeppesen PPL book was packed with info but I personally felt it a secondary resource when cramming for the exam. The fact that i still read it and learn something shows the quality and quantity of information it contains.
Then of course there are the practice papers or "cheat sheets" which of course assist with the pass.
Maybe I did it wrong, but I studied to jump through the hoop. Now I read to become a better aviator.
Hope this helps,
Best,
