Sequence of Exam Sections
The two AWA sections are administered consecutively and always before the Quantitative and Verbal sections of the exam. However, the two AWA sections may appear in either order. Here's how the two AWA sections fit into the overall format of the GMAT CAT:
CAT System Tutorial, Practice, and Demonstration of Competence
Analytical Writing Assessment (60 minutes)
Analysis of an Issue (30 minutes, 1 topic)*
Analysis of an Argument (30 minutes, 1 topic)*
10-minute break (optional)
Quantitative Section (75 minutes)**
Problem Solving (23–24 questions)
Data Sufficiency (13–14 questions)
Total number of questions: 37 (28 scored, 9 unscored***)
10-minute break (optional)
Verbal Section (75 minutes)**
Sentence Correction (14–15 questions)
Critical Reasoning (14–15 questions)
Reading Comprehension (4 passages, 12–14 questions)
Total number of questions: 41 (30 scored, 11 unscored***)
TOTAL TESTING TIME: 3 hours, 20 minutes
* The two AWA sections may appear in either order on the exam.
** The Quantitative and Verbal sections may appear in either order, and the different types of questions included within each section are interspersed.
*** Either 9 Quantitative and 11 Verbal questions or 10 from each section are unscored—totaling 20 unscored questions on the exam altogether.
