I'm giving the GMAT in two weeks time so right now I am focused on solving all the problems in the OG12
. In the quant section I have no problem with Problem Solving. However, the Data Sufficiency is giving me a REALLY hard time. I am doing 30 DS questions per day and I get half of them wrong! I know they are hard by default but I haven't seen ANY improvement in my performance since I started preparing one month ago. I feel very disheartened because I am aiming for a 700+ score. I've read all the Manhattan GMAT guides
and they've helped me a lot in the other sections but not for Data Sufficiency.
So what should I do? Keep solving DS problems and hope that a miracle happens? Or maybe, try some other textbooks?
