GRE Tip no.3: 500 hours
You need to give 500 hours before appearing for the exam. Many students come to me and ask how much time is required for the preparation of GRE and I tell them that you need to give 500 hours of your time to the preparation of the exam in order to get a good score, and it is entirely up to you whether you give these 500 hours in a month or in 6 months.
