Thats a great idea for direct learning.
I had the impression that you were studying and would probably be tested on the topics. If that is correct then you need to practice intentional activation. The reason for intentional activation is to build the connection with your inner mind to bring forth the information 'when' you need it. Without this practice you can find yourself 'living' the information but not being able to explain it. The effects can be so subtle that you don't even realise that you know it.
I think you risk undermining yourself wondering 'what if I didn't get it? Especially if you cannot answer the questions in a test because you don't recognise them in relationship to the question.
Play with it yes... practice any exercises presented in the text books you Photoread to bring the information to the conscious mind, for recognition. If you're not getting the results you want work on activation.
