I have some problems. I am needing your help.
1, After step3 PhotoReading, should I catch key words right now？or wait for half an hours？
2, I don't know How to catch them, as we know ，a book have lots chapter headings , so if I should open each chapter titles and each section titles to catch key words？
3，During postreview, How many questions should I ask？ How much time for each activation layer？
4，I don't know How to catch key words,which make me unhappy. If it's too long for I spend 3 hours to finish Activation？
