I am ecstatic to say that I passed my PMP exam the first time! There were 2 key components that really helped me. I am a visual learning so for each chapter I wrote ITTOs on large post-it notes and put them on my walls. My walls looked like table 3.1 from the PMBOK. Not only did this force me to look at them every time I passed by but it also created a mind map for me. Brain dumps were also a big part of understanding the material and creating a mind maps.
