Your score on the essay section of the GRE exam is used by graduate schools to evaluate your writing and analytical skills. Two separate trained readers will read your essays. They will score each essay based on many factors, and the scores will be combined and averaged. Scores are given on a range from zero to six, in half-point increments. The ETS provides the criteria that are used to score the issue and argument essays. Although in the essay section grammar and spelling are important, it is much more important that you concentrate on writing a coherent, complete, and persuasive essay.
