The computer based gre contains three sections. Analytical writing, Quantitative reasoning, Verbal Reasoning. The unscored & Research sections can be skipped. The most frustrating is that you have to write before you can give the Verbal exam which you will be very anxious ( i bet).

Section	Number of Questions	Time
Analytical Writing	1 Issue Task*	45 minutes
Analytical Writing	1 Argument Task*	30 minutes
Verbal	30	30 minutes
Quantitative	28	45 minutes
Unscored**	Varies	Varies
Research***	Varies	Varies
