Hello,dear

Well ,you can appear as much times as you want there is no limit in gre exam, but the thing happen is that if you attempt many times it would be counted and some graduate schools may average  your scores ,and as well money waste.

Hope this will help you!!

Hello dear

You can take the GRE revised General Test once every 21 days, up to 5 times within any continuous rolling 12-month period (365 days). This applies even if you canceled your scores on a test taken previously. If you take the paper-delivered GRE revised general test, you can take it as often as it is offered.
