Hi MohitVerma,
There are a variety of different factors that can impact your 'focus' during the Exam - and many of those factors occur BEFORE the Exam even starts. To put yourself in the best possible state during the Exam, you have to consider how you are handling the mental, physical and psychological aspects of everything leading up to the start of the Test. For example, what type of sleep routine do you follow (and is it consistent?)? What do you eat for breakfast - and what might you eat during your breaks during the Exam to help re-energize for the next section? What time of day are you beginning your Tests? Is the week leading up to your Official Exam exceptionally busy or causing you undue stress? Etc. During the Exam, it helps to have a set of specific Tactics that will help you to break each prompt into small pieces - so that you don't get 'lost' in any prompts that are wordier or more layered - and those skills are gained by training for the GMAT in a specific way.
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) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
