I got my final results broken down by test number , 1.5 weeks after taking the full test. The score of 80 that I saw previously on the prmia website was actually an average score across all 4 exams( rounded to 80).
As far as the PRMIA exam is concerned,in addition to reading the handbook twice from cover to cover, I think the Kesdee exams and Riskprep tests are very good for test preparation.
