@Ali2...study ur GMAT very well, things like sentence correction, logic, etc for verbal.........data sufficiency, word problem leading to questions, etc for numerical...I believe they sent U a mail, and I bet the mail contains where U ought to concentrate on.
You will be given about 45 questions for and hour......U ought to be fast and still very precise and accurate in ur answers.
I wish U the very best bro...represent NHJ very well at the venue..................one love bro.
