How convenient preparation got

I did not have to do much to be a premium member of the GCPM online practice tests. The mode of subscribing to the same is easy and simple. Once I was granted the access, I began attempting the mock tests. After a couple of tests, I compared my performance and realized my mistakes. All this made my preparation quite convenient. When i sat for the actual certificate exam, i was not a bit nervous and cleared the exam at first attempt with 87%.
