Try re-writing the information in a different way. Doodle spider diagrams on paper or on those stick-on-the-wall makeshift whiteboards you can buy - they're fun and help. Sit down and learn a couple pages, then doodle the main bits you remember on the white board, go back and check what you got right/wrong or missed out. I find that I don't know if I really know something or not unless I put the book down and test myself on it, not just read over notes or make notes and pretend it's gone in when for me it really hasn't.
I think you're doing a reasonable amount (the highlighted stuff) for a day, actually. I'd like to suggest that you're perhaps assigning what is, in reality, a 3 hour job, to a one hour slot. That creates the opposite of a sense of achievement. Be realistic in assigning certain slots to do certain things and you might find you get everything you want to done in the day.
