Doing questions (particularly practice exams) engages the brain to a greater extent, than just memorising notes. Then again, you can memorise your notes either passively or actively... for example in psychology, one might ask "what does dopamine do?" I would then draw a venn-diagram or flow chart and list how the definitions for dopamine vary according to mental illness and learning, thinking from the examiner's point of view.
In essence, if you try and memorize your notes in the context of a potential exam style question(s), then you are actively memorizing your notes, and perhaps, this could be an adequate substitute for doing heaps and heaps of questions.
Or maybe, you could set a day aside for actively memorizing your notes, and on the next day, just do questions? It all depends on how you learn best, what sort of study timetable you've set for yourself, and what you're trying to achieve by the end of 3 days/ a week/ a month.
