There are many books available for preparing PMP. Some books are really wonderful to read and completely logical. Harold Kerzner's book is one of them.
Some more to share in mixed form:
1) Project Risk Management chapter is excellently written in Rita 8th edition. I think almost all PMP aspirants are good on Risk Management topic. I feel we need to be prepared for tough questions pertaining to EMV calculations. Better to practice more on EMV.
2) Quality chapter needs to be gone through several times. Edwel 5.0 book can provide extra information on this topic.
3) Scope, Time and Cost Chapter - I feel PMBOK 5.0 is more than sufficient. However, better to prepare TCPI calculations for complex situation. Also better to practice network diagram calculations for complex situations as problems on network will take considerable time to solve.
4) Stakeholder chapter – Rita 8th edition looks to be insufficient for this chapter. However, PMBOK 5.0 gives enormous clarifications on this chapter. J. LeRoy Ward & Ginger Levin’s questions on this chapter helps a lot.
5) Project Procurement Management chapter – Once again I feel PMBOK-5.0 has given sufficient information. But Edwel, Rita 8th Edition also gives good amount of information.
6) Closing Process Group i.e. Close Project or Phase Process + Close Procurements Process - Fastrack V8 questions gives minute information on this so that concept becomes crystal clear.
7) Fastrack V8- Very good quality questions but only one line answer is given for many complex situations.
8) Heldman 8 – all questions needs to be practiced.
9) Oliver 175 & 75 – Needs to be practiced several times. It gives new terminologies normally not found in regular books.
10) Head First – Many times I sat for the exam for 200 questions + all individual chapter’s questions. Excellent clarifications are there for all questions. Some mistakes as well as missed questions are also appeared to be there. Actually this questions creates confidence in us for taking further other mock tests.
