Hi Nevine,
You're not alone in underestimating the difficulty of the PMP exam. We're pleased that you passed and glad PM PrepCast offerings helped on your second try. They were my main source of training, though I did watch a couple of Aileen Ellis videos out of curiosity, too.
When you are ready to start earning PDU’s for PMP recertification, check out the PM PrepCast’s offerings:
