alpha state... you have the book right? Well... I truely authentically learned PR this weekend with all my prior knowledge of PR. I went to the Health Science library at UT memphis where my parents work. I took a few books on neurology and brain stuff. PRed them and PRed a medical dictionary.
From my experiences, I gained A LOT through Post view and a fast preview. After a while, like about 10mins or so, I went back to activate stuff. It is pretty interesting how much you can gain from filling up the skeleton of the text.
Hope that helps.
