Thank you- I realized too late that this seemed a predominantly British forum. Off I go hunting for a US forum!

I just called and checked my score results. I got a 600 (77th percentile) and I am wondering if I should bother sending it into my schools. All of them don't require it, but some do recommend it.
The rest of my application looks like this:
A GRE verbal (640 = 91st percentile), quantitative (780=90th percentile), analytical writing (5 = 77th percentile)
I am applying to Ph.D. programs in immunology/ infectious diseases in a spectrum ranging from the U.Cs to safeties. I obviously want to go to the U.Cs. I had research experience throughout undergrad study and my GPA's around 3.8. I am currently a senior. Would sending in my subject score negatively affect my chances of being accepted into the U.Cs?
