I recently wrote a comprehensive article on obtaining a PMP certification on Train Signal Training. It lists out the activities you need to undertake to register for the exam, the pre-requisites you would need and the exam logistics.
Alongside, I have shared study tips in brief that will enable you to master the PMP with least effort.
I am currently involved in preparing PMP training deck at the place where I work. V4 looks a lot different than V3! I have heard that it is a lot harder as well.
