I've taken the GRE twice now. The program I'm applying to doesn't have a requirement but says the average accepted student is about 60th percentile. I didn't really study for them and I got 154 verbal(63rd) and 154 (56th) quantitative. The writing isn't back yet, but I'm usually a pretty good writer I'm not too worried about that. I have time to take it once more. Should I try again or not bother if the rest of my application is pretty strong?
