Hi Kevin,
I have not appeared for exam but think that you can try below strategy if looks good.
1. Considering 60% in the mock exams read and understand PMBOK on Role of a PM , Initiation and Closing for next two weeks.Take prepcast exam every weekend and check the performance overall and mainly on Initiation and Closing process. Check the gaps and wrong answers. Target for at least 65% in these two weeks.
2. Repeat step 1 for Planning for next two weeks with revision on Initiation and Closing and check performance.Target for at least 70% in these two weeks.
3. Repeat step 1 for Execution for next two weeks with revision on Initiation,Planning and Closing and check performance.Target for at least 75% in these two weeks.
4. Repeat step 1 for Monitoring & Control for next two weeks with revision on Initiation,Planning,Execution and Closing and check performance.Target for at least 80% in these two weeks.
Understand the process and terms example Project Charter, when it gets created and what all information it will have. After 8 weeks you will complete all the mock up test and revision of PMBOK.
