Hi,
the PMP Exam Simulator offers a special mode called "Timed & Learning Quizzes " where you can either choose random questions, questions by domain or questions by knowledge area. Here you can check your knowledge module by module.

In the "real" exam mode, you will always get 200 questions with the specific percantages for each area.

I wanted to ask if it is possible to study and practise on the exam simulator domain by domain (e.g. Initiation, Planning, etc) or Module by Module (e.g.. Project Integration Management, Project Time Management) or am I required to first finish the whole 13 modules before starting the test?
