All depends on where you want to go really. And although I agree with most of what ddakjiking is saying, if you score high enough and are not applying to the TOP schools....they can and will find scholarship money for you.
Stanford seems much more concerned with soft factors and is thus considered an admissions "black box." If you have killer rec letters and a solid personal statement, I don't think it's worth it
You can apply and retake in June and then decide if you want to reapply next cycle based on your new score and your acceptances and scholarship offers.
