The problem with finding the most important information, unfortunatly, depends on the instructor. If the instructor is reasonable sane, you should have no problem finding what is important in the textbook. However, some instructors will put wierd questions on the test, ones that really are not on important points but minor details. I don't know why they do this, aside from screwing up students and maybe trying to stop people from Photoreading and speed reading. I had one of these professors. After the first test where I used Photoreading, I gave myself suggestions to find the most important information IN THE PROFESSOR'S MODEL OF THE WORLD. This worked. I used these suggestions before Photoreading and when I hypnotized myself before the tests.
