For manual activation, it's actually the time when I am doing questions based on that txt or when lecturers are going bits that I've photoread.
but most of time is when I superread and dip each chapter.
I'd relax, and tell myself "relax, your concentration is absolute, and you will dip all the information that is useful or you don't quite comprehend in this chapter of the book"
and I will then superread the chapter. My superread technique is just basically softfocus the page and zoom from left to right of the text, like i see 4 lines of txt everytimem.
and this would take about 5min. Then I'll do the same with the other chapters.
after30min i'll take a rest for 5 min then resume superreading the same chapter again.'
NO i haven't done a mindmap because I haven't been absorbing enough information to do so.
