Hi Azizakaria,
In a prior series of posts, you mentioned how you were planning to take the GMAT on March 12, your score goal was 650+ and you were facing an April application deadline. Is all of that still true?
Since you've been studying for several months now, you should have taken a number of FULL-LENGTH practice CATs. How have you scored on each of those CATs (including the Quant and Verbal Scaled Scores)? That information will help define what you should be focused on right now.
GMAT assassins aren't born, they're made,
