The GMAT Analytical Writing Assessment (AWA) consists of two, 30 minute components. One asks you to analyze an argument, and the other asks you to analyze an issue.
The scores that you get in the GMAT AWA section are independent of the scores that you receive for the objective type questions of the GMAT test. While you are graded on a scale of 200 to 800 in the GMAT Test based on your performance in the objective questions, you will receive a score that ranges from 1 to 6 for your performance in the AWA section. 6 represents a very high proficiency in the GMAT AWA section.
