fossola31 .. the best way is to first give yourself time to study.. at least 4 months with the amount of material there is.
you need to do a lot of practice questions. and make questions your leaning aid as well, learn from each question. a question on any specific topic or item tells you which one thing is correct about it and which 3 things are not correct.
the best way is to go chapter by chapter in the books and make small learning points and notes.
are you using the next-through slides?
