Is it possible to impress a committee for (science) graduate school applications with GRE general test scores? What about with the non-math sections? Would even a perfect score or close to it on one of the sections stand out, or would it still just be a litmus test that doesn't really make you stand out? And regarding the subject test. Is it another litmus test or can it help/hurt you? Does a mediocre/average grade hurt you? I feel like the GRE can only hurt you if you do average, and doesn't really help you if you do above average. Is this true or am I underestimating its value?
