More advice, I hope you do not mind:
I would dive in forthwith.
Just Photoread them upside down and turn the pages from the back of the books forward, even Photoreading thus a dozen books.
Concentrate singing or chanting as in a lullaby your chosen affirmations while you Photoread.
Do not attempt to activate these series of tech books. Keep to one theme to you, or by subject.
Then in a less than a week go dig into the material as in 'a lab experiment' or get your hands into the subject where you must 'know' to procede.
Use your hands to activate. This is a key to getting knowing into experience and on to mastery forthwith.
Kind Regards,
