1. It will be blurry.
2. Learn the system first on non-academic book. Short 200 page self help books are ideal. 2 or three of them under your belt should make it easier to address the academic books.
3. I did the home study course consecutively for the first 6 or 7 days then I didn't do the final part of the course till two weeks later. So it worked for me it can work for you.
4. If the book is a course work book for a grade or exam. Use all the steps of the system and activate it. Your level of comprehension should be the same or better than traditional reading.
