Hello Carlos,
Over the past few months, our students have told us again and again, that the questions in The PM Exam Simulator are 'very close' to the questions on the real PMP exam. So I can say with confidence that if you achieve a good score in the simulator, you should be able to achieve a passing score on the real exam. However, there is really no guarantee. The simulator is only available in English.
I have two considerations for you:
First I recommend that you listen to this interview here that I did with Kevin Reilly:
www.project-management-podcast.com/index...pmp-exam-three-times
-- We talk about reasons why people have failed their exam.
Second, please watch the webinar "10 Steps to becoming a PMP". You can find the webinar on this page here:
www.project-management-prepcast.com/webinars
-- In my opinion, because it has been 10 years since you last studied for the exam, you are going to have to 'begin at the beginning" and study everything again. This webinar will help you.
