Each book is 2000 pages for a total of 40,000 pages of technical material?
Well no matter, organize these books in groups of 3-4 that are close as possible to one central idea. This could make 5-6 groups of 3 or 4 books each.
Do one group per week using the same Photoreading discipline you have already successfully employed.
Only add more meditating on every single diagram and picking out the terms, ideas and concepts in each where you meditate on them and then go back and meditate on those diagrams again back and forth. Last day of that week, mind map that group as one whole idea.
Repeat out for each group until the whole is down now sixs weeks later.
Now review each weeks mindmap and mindmap the whole of it, that is all 20 books.
Kind regards and good luck no that testing!!
