Hi Basim2016,
Many Test Takers face pacing issues in the Quant section, the Verbal section or both - but it's important to remember that pacing problems do NOT exist on their own - they're the results of OTHER problems. Since most GMAT questions can be approached in more than way, you have to consider how YOU are approaching questions; even if you are getting the correct answer, you might be doing so in an inefficient fashion that is costing you too much time. By extension, if you're comfortable using faster Tactical approaches, then you can choose the fastest approach for each question and avoid much of the anxiety that most Test Takers face.
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far?
3) How have you scored on EACH of your CATs/mocks (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
