I would recommend that you try to have at least on 30-minute activation session on each of those additional textbooks. Doing the PhotoReading step 3 techniques alone does not guarantee your conscious mind will be able to bring the information up when you need it.
If you have at least one activation pass, you'll burn in those new neuro pathways which will enable your conscious mind to draw on more of the material that you absorbed during the PhotoReading step.
