Totally Confused

[coolsammy35]

Hey guys it's been few weeks that I had been collecting information about GMAT and now that I had inscribed everything in my mind I have become confused.

Actually,I am dentist with 2yrs of experience and planing to do MHA (Masters in Hospital Administration),I had gone through many colleges website's that are offering MHA,they say that they accept GRE and GMAT scores,so my questions are:-

1) Which is the exam that i should stay with ?

2) What is average score of GRE that a college offering MHA looks for(KEEPING IN MIND THAT MY GPA IS BELOW 3,its quite frustrating) ?

3) Which is easier GRE or GMAT( I heard its GRE) ?

4)Is it worth taking a GRE considering the fact that I want to do MHA not any other graduate course ?
