No. GRE scores are one component of your application, and they are weighed in combination with your undergraduate transcript, your statement of purpose, and your letters of recommendation. Low GRE scores may prompt reviewers to consider whether they are consistent with the rest of your application. If they are viewed as an aberration from an otherwise strong record, their negative impact will be reduced. By the same token, low GRE scores that are in keeping with weaknesses in other areas of the application may reinforce an overall lower rating. To give you an idea of typical GRE scores, over the past ten years, GRE scores of enrolled REECA students (the average of Verbal, Quantitative, and Analytical Writing percentile scores) have ranged from 50-95% with the average being 75%. Average GRE scores are 73% Analytical Writing, 66% Quantitative, and 90% Verbal. Median GRE scores are 84% Analytical Writing, 69% Quantitative, and 95% Verbal.
