With the GCPM practice tests online, i did not have to worry about my preparation for the GIAC Project Manager certification exam. I was always focussed on attempts that i made and how to up my score for the next attempt. Even my doubts that i had in a couple of topics got solved automatically as the questions in the practice tests were from all the topics based on their weightage. So, there was no such topic that was left out for preparation. I was pretty much confident in the end because it helped me towards my goal of clearing the exam.
