Folks, 

I have been going through Head First PMP by O'Reilly. While the topics were pretty good and exhaustive, the exam answers seem to be wrong. Did anyone face this before or am I the only one. I found out one discrepancy where the calculation was right but the option was wrong. I am not worried about the credibility of the other questions/answers from that book. 

Moving on to Rita Mulcahy's 8th edition. 

Any suggestions?

Thanks!
