Hi, considering your score as of now, you might need to brush up some English concepts before jumping into the verbal part of the GMAT. A great book to work on the basics is the "Foundations of verbal" by
Manhattan Prep.
I suggest that you also start reading GMAT like material from sources such as "The Economist", "The Scientific American", "New York Times", etc.
In case you are not very fond of reading magazines, you might check out this post for some great book suggestions to improve both, your reading and your natural instinct of judging material in English.
