poor quantitave score

<p>hi all, i'm applying for a phd in either cognitive neuroscience or neuroscience at mit, yale, brown or nyu. i took my GREs yesterday, and got v800/q700. i thought it was pretty alright, but two other friends who took it with me got 800 each for math, and l i read somewhere that the average accepted score for the unis i'm apply to hovers around a 750-775? that's kinda scary. </p>

<p>is 700 is enough for a top-tier university? and how closely do universities look at these scores anyway? </p>

<p>thanks in advance! :)</p>
