1. Read the PMBoK 5th edition three times before taking the exam. In that, use mind mapping to take notes, once. On scope, quality and procurement knowledge areas, there will be some questions straight from inputs / tools and techniques / output; In risk management the order of events (the risk life cycle) is important; In quality management you get many questions on planning and QC tools etc. So reading PMBoK is crucial. If you can get some experiences PMs to explain PMBoK concepts, from beginning to end, with examples and stories, you should grab that opportunity. Technical documents can be boring to read by yourselves.
