What is a reasonable analytical writing GRE score for a science/math/engineering programs? I had something like a 4.5/6.0 which seems kind of mediocre. I talked to some professors about why the general GRE is required, but they said that it was mainly aimed towards testing international students' grasp of English and their basic writing skills. Is it worth retaking if my other scores are good? How significant is the general GRE score for such programs?
