I found the books the best for me, its just a matter of time. Do the practice questions after each chapter and keep going over it untill you know it.
I also go hold of the Oxford cd, didn't suit my style of learning but he questions are a good tool as they assess where your weaknesses are. The ppl confuser should put the iceing on the cake as you run up to the exam.
There are lots of trick questions used which is a bit daft but thats the way its done, so make sure you read the questions and answer them, not what you think you saw.(took me a couple subjects to get my head around that)
Save yourself a nice easy one to take just before your skills test or at the end of the 18 month spread you are allowed. I made the mistake of getting them all done in 3 months then had a nightmare with weather and timing which ment i had to retake them all where as if i had left HPL unitll the limit it would not have been a problem.
Have a great time learning it all, it is all useful, just not all at once.
