How is GRE score 1330?

Answer 1

If 1330 is the sum of the quantitative and verbal tests, each out of 800, then 1330 is above average but not very high and probably does not indicate suitability for graduate studies. However, many graduate schools will take applicants with low scores anyway even if they are not equipped to do good work yet, or if they are concerned with only a very narrowminded focus reflected in e.g. 1330=790 verb +540 quant.

However a 540 in quantitative suggests the applicant cannot count how many sides a triangle has, and a 540 in verbal would mean that the applicant cannot use words with more than two syllables, or sentences with more than one comma. Graduate school can be very difficult in those cases, and writing academic papers for publication would be impossible.
