I wrote gmat last year and got a 700. During this summer I have studied to retake it and I am aiming for >730.
On my last official Cat I got 740 (49Q 42V). I had 5 wrong answers in PS and 1 in DS. There were 3 wrong answers with a common theme, namely questions regarding series of sums or integers (like, how man integers are there between x and y that is a multiple of 2 but not a multiple of 3). I have and will keep practicing on these type of questions until its time to write the test. The other wrong answers were not because of a lack of knowledge in math, but rather because of the difficulty of the questions. I couldn't finish the questions quickly enough so I guessed and continued with the test. I have a
magoosh membership which I use to study math if you are wondering.
Regarding the verbal part, here it is the SC that is pulling me down. In total, I had 6 wrong answers, 4 in the SC and 2 in the RC. I have the Manhattan SC book which I find very good and it has helped me to increase my SC-score quite a bit. My plan here is to keep reading in the book and applying the knowledge from the chapters on relevant questions from the OG. I do not have a specific plan for CR and RC except that I have found some nice books that I read when I am done studying for the day.
I also have one more official Cat left to do, do you guys have any idea how I should use it?
I am grateful for any tips you can think of.
