I'm only a beginner PR, bought the course about 6 months ago but doing it just now. Only on my second pass through the tapes. Just PR'd a biology text but found that about half way through, I started to get tired and my concentration began to fall. Should I do it by chapters? Also, because the pages are bigger I was't sure that I was actually seeing all that I was supposed to see. No problem with the blip or anything like that, did all the preview etc... blah blah blah. I know that PR will (eventually work for me) I just need to use it more and go through the tapes a few times. I know that my concentration has improved a lot and I can shut off outside noise when reading (something I could not do before) normally. I know it takes time and I mean to go through the tapes at least 2 dozen times. What about articles and stuff on the computer? Where do you actually focus? 'Cause there's no blip to see? Would you imagine an X in the middle of the page and focus on that? Thanks.
