<p>Which test is harder?</p>
<p>I only took the GMAT, so I can't make the comparison. But I know that all of my friends that took the GRE had flashcards trying to memorize vocab words and suffixes and prefixes, while for the GMAT we didn't have to do any of that.</p>
<p>I think it depends on your own strengths and weaknesses. To grossly oversimplify, take the GMAT if you are better at math, and take the GRE if you are better at verbal.</p>
<p>^ agreed ^_^</p>
