TOPIC: CAPM exam , help

Dear all,

i will have my capm exam next month. and actually i feel a little bit lost. In some exam simulators i have 69% but with this system by PM Prep Cast im always 52%. its a very big difference and takes down my motivation.
Any idea or tip how should i make it? actually im reading ritas book and the pmbok but checking this exam results i don't know what im doing incorrect .

looking forward to read some of your answers. regards
Miguel

Miguel, I'm sure others will come in and comment, but my thoughts are to read the explanations in the questions to help you understand why you didn't get an answer right. Then to study the relevant section of the PMBOK(R) Guide or the equivalent section in the prep book to go over the concepts.
