The Unified Parkinson's Disease Rating Scale (UPDRS): Status and recommendations. For a full list of contributors, see Appendix 1. Abstract.

However, we can tell you how much time other people spend in their preparation. Using data collected from nearly 8,000 GMAT test takers, we can see that 44% of the test takers spend at least 51 hours preparing, 65% start preparing at least 4 weeks in advance, and those who do better on the GMAT tend to spend more time preparing. Donât let the charts fool you.
The only restriction is that you can only take the GMAT exam once every 31 calendar days and no more than five (5) times in a rolling 12-month period. If you take the GMAT test more often than allowed, your new scores will not be reported and you will forfeit the entire test fee.
