If you are interested in reading it go ahead. If you are doing it for the purpose of trying to raise verbal score this will probably not help much, and may even be counterproductive. You don't want to use outside knowledge when answering verbal questions. Its important not to get the philosophies of each person affecting your perception of the authors POV in verbal passages. You are better off doing a bunch of practice passages.
Instead of trying to increase your scores by doing a lot of different things, you will probably be better off really doing postgame review. If you look at others who have posted after doing well, many stress the importance of this, which is often neglected.
