An awesome study guide for the certification

There are so many study guides available both online and offline that it becomes difficult to choose any one and how to choose them is also a big trouble. I chose the best resource to prepare for the AgilePM Foundation certification exam on the basis of three factors - firstly, it should be comprehensive. Secondly, it should be dynamic. And thirdly, it should be easy on my budget. And i encircled the AgilePM Foundation Level online simulation with paid question bank after giving the sample test.
