300 seems like a reasonable cutoff for GREs, as that would be around 40th percentile for both sections. In fact, one of the programs I applied to explicitly stated that they would not consider anyone with a Verbal score below 155 and a quant score below 150.
Hello! I applied to 4 anthropology programs, and am now waiting like most of the rest of you. I haven't been active on the board prior to this, but I wanted to chime in on the "should I contact my potential PI" discussion. I think DanJackson hit the nail on the head. You are an adult applying to a job, and there's no reason you can't reach out to your potential supervisor if you have a reason to do so (a good test for necessity is to type out the email, and then read it as if you were the PI receiving it). If doing so were to cost you your position in that person's lab (and really, it probably won't), you most likely wouldn't want to work with them anyway. Anyway, thanks for all the postings here, it's been a great resource while I wait things out.
