Best study note for PRM?

(You can answer in Thai.)
I would like to sit PRM because I would like to find risk management job.
Schweser has study note for FRM. It does not have study note for PRM.
What is the best study note for PRM?
I plan to read only a study note from 1 source and take the exam.
I have no finance background.
My educational background is computer science.
I am good at computer's math but don't know much about finance math.
Thanks for your kind help.
