how many times should i take gmatprep test before taking actual gmat? please help.
There is no specific "number" of times you should take it . I'd say take it as many times as possible , because even if you've taken the test 5/6 times , you will see at least a few new questions . Don't attach too much importance to your score after 1/2 retakes though , because your score will most probably be a bit inflated .
