Just do as EK4457 said. Somedays you will struggle to do about 50 and others you will just breeze through a hundred or so and feel like you can keep going. Also as EK4457 said, alot of the questions in the feedback are the same question wrote in a different way repeated several times over.
I would say though that for a person to remember the majority of the feedback that you are going to have to be able for coping with copious amounts of information over a short period of time and being able to retain it. Not all people are capable of doing this though. There was several in my class who I would by no means call stupid but were just not able to absorb the huge quantities of information. All people work at different levels. I have always thought of History as a good indicator. A subject were there was no real theory involved but did require a person to remember huge quantities of information.
