Plan studies - RMP Exam

Dear all friends from Pmzilla,

I am going to start my studies to hold RMP certification and need some tips about this exam.

- last month - Read 1x Rita Mulcahy RMP exam based in fourth pmbook edition 

- last month - Read 1x Practice Standard for Project Risk Management 

Just bought Rita Mulcahy 8th edition and Pmbok 5 from PMI.org

So, my questions are;

Need i read all chapter from Rita book or just Risk Management?

Need i read all chapter from PMBOK or just Risk Management?

After read this books i will buy Rita RMP Fastrack or ucertify RMP questions.

Thanks a lot,

warmly,

Juliano.
