Hello,

Preparing for GRE takes from around 3-6 months depending upon the degree of required knowledge you already possess as well as well as the type of preparation which you are opting for.

For most Indian students who have studied math till class 12, the Quant section is easy to prepare for and only requires specific revision and practice. This usually takes around 1 month if you plan on studying 1-2 hours per day.

The Verbal section usually requires a greater amount of preparation, especially while going through the vast recommended vocabulary for GRE. This may vary depending upon your proficiency in English and your verbal abilities. The best way to begin preparation for the verbal section is to give the preliminary vocab test provided at the beginning of 'Word Power Made Easy' by Norman Lewis.

Preparation time for self study (2-3 hours a day) would take around 3-8 months, depending upon your level. On the other hand, coaching classes offer 3 month programs as well as 1 month preparation programs for GRE preparation.
