Dear all

i am preparing for the exam. up today i read the rita 7th edition almost twice and the pmbok just once quickly (the language used in the pmbok is not that very generous so my feeling)
I tried for the very first time the 175 questions from oliver and i found them terrible difficult, the form and language used is very very new to me,  this compared with those questions from the pmbok/rita. Thus i gain a result of 53% (considering all them with formula are not been answered since i do not have memorized the formula yet). Just comparing, the FIRST time going trough the questions at the end each chapter either pmbok/rita i obtain almost the same result partially higher up to 65%.  In addition to i was wondering - reviewing the results- where oliver refer to additional pm books, apart the pmobok of course.

What is also the expected form/language while the real exam? shall i come confident with oliver its "form" or are those much more difficult than the real exam?
In addition to that, why is oliver refering to additional lectures? do I also need to study some more books for beeing really prepared?

best regards

pietro
