having some difficulty grasping certain concepts
The basic technique remain the same. However since the text is technicial and more challenging for you, you'll want to spend more time activating to gain a better understanding. Photoreading the book every day for a couple of weeks will help.
Remember to treat each chapter as a book on it's own when activating. Give it as many activation passes as you require. prior to activating the chosen chapter photoread it, plus the 2 chapters before as well as 2 chapters following. By photoreading the other 4 chapters as well you round out you inner minds knowledge as it relates to the chapter you are activating.
Make a Mind Map of each chapter as you activate it. Quickly review it prior to activating the next chapter to aid your long term memory of the information.
Good luck with your studies
