If you are going to purchase, from certkingdom...Be aware that their life time membership is not life time. When I purchased my life time membership in 2016 it was $50, with the guarantee that I would have access to all certifications. I just logged in trying to access but they are asking me to pay again, this time the fees are extremely higher, $50per month, $99 3months, $299 12months and here we go $599 unlimited life time???????? So I contacted them, and low and behold I was told it was not an Unlimited Life Time Access but a 3 year access, which now has expired are you F****** Kidding me... Their new Unlimited Life Time Access is $599, maybe 2, 3 years down the road their terms and conditions will change, and you will be just as disappointed as I am now so BUYER BEWARE!!!
