I recently graduated from college and decided that it would be a good idea to go ahead and get the GMAT out of the way. I've invested about 3.5 months studying for this test, and my scores are as follows:

MGMAT 1 = 720, (Q43, V45)
MGMAT 2 = 680, (Q43, V39)
MGMAT 3 = 730, (Q48, V41)

I feel that I've spent a great deal of time and energy attempting to improve my scores, and I'm certainly seeing the benefits of it all. However, I've just started to see some indications that top schools that I am aiming for applying for in about 4 years (Harvard, Stanford, Wharton, MIT, etc.) may prefer scores that are no more than 2 years old.

Is this true, or some type of myth that gets perpetuated around these message boards? I feel that I can reasonably get my score up to 750+ level, but I'm not sure how to approach this situation if my scores, despite being 'technically' below the 5 year age expiration, are being judged as inferior to more recent scores from other candidates.

If anyone has a definitive answer on this, I would greatly appreciate it. I've seen people say that 4 year old scores do not appear less competitive in the minds of admissions committees, and I've also seen people say that I may as well re-take it again in 4 years. What is the real answer to this question?

Thanks.
