What is your budget? Classroom training will cost you 2000-2500QR. While online PMP preparation course will cost you 50-70 USD means 250 QR approx. For online course I suggest "izenbridge" site. Search on google you will find the details. I am a PMP (passed in Dec-13 with 5 Proficients) and I relied on online course as cost was the main constraint for me.
