The score / grade range in the GRE test are as follows -
Verbal reasoning- 130 to 170 (in 1 point increments),
Quantitative reasoning -130 to 170 (in 1 point increments).
Analytical writing -0.0 to 6.0 (in 0.5 point increments).
In GRE test scaled score percentiles are considered instead to scores obtained.
Even if no question is answered correctly, 130 is the lowest possible score. However in such a scenario, both the verbal reasoning percentile and quantitative reasoning percentile will be < 1 and in case of a scaled score of 170 the same will be 99 and 98 respectively.
