I found this reading to be quite interesting, as I think back to my college study habits.  We had old tests from previous semesters that we studied from, I wondered at the time how much I was memorizing VS absorbing.  Some things I had to re-write to understand and pictures help a great deal for me, especially if I read and re-wrote the material on or around the picture.  With all that being said, I was rather surprised with the outcome of some of the above study.

Maybe I will have to give my students mock exams  . . .
