After taking a few practice tests, I am have noticed I have significant weaknesses in a few sections which I will need to improve on if I want to score 670+. Lets start with the first section which I am weak in, Data Sufficiency. I am weak in this section especially number properties, absolute values, and the other math topics. Another section I am weak in is the sentence correction. What are some guides and practice problems you guys would recommend using to improve on these sections? I have been using the Manhattan guides and OG 13.
