When should I study for Project Integration Mgnt ?

Folks,


I'm currently studying from Rita's PMP ,6th edition book and after I completed the Project Integration Management, I decided to do some questions from the PMFast track. The problem is that I'm getting questions which are related to other chapters , such as Scope , Time & proffessional & social responsibilty. I could not answer these questions since they are not related to Integration Managament.
 


My question is should Skip Integration managent chapter for now and complete studying the other chapters then I come back to the Integration managent and study it as the last chapter?


Any advices will be higly apprecated,


 


 

 My suggestion is to read the entire book first time before start attempting questions on PM fast track else it can be confusing.
