Scoring of Analytical Writing Assessment (AWA) section:
The Analytical Writing Assessment (AWA) section of the GMAT is scored separately on a scale of 0-6. Two independent human graders evaluate each essay based on four criteria - Ideas and Analysis, Development and Support, Organization, and Language Use. Each grader gives a score on a scale of 0-6 for each criterion, and the two scores are averaged to obtain the overall score. If the scores given by the two graders differ by more than one point, a third grader is brought in to evaluate the essay.

Contribution to the overall GMAT score:
The AWA section does not contribute directly to the overall GMAT score, which ranges from 200 to 800. However, it is an important component of the GMAT exam and is considered by business schools during the admissions process. A strong AWA score can positively influence the overall perception of an applicant's analytical and writing abilities.

Significance of the AWA section:
The AWA section is designed to assess the test-taker's ability to analyze complex arguments, articulate thoughts clearly, and support ideas with relevant examples and reasoning. It helps business schools evaluate an applicant's communication and critical thinking skills, which are crucial for success in the MBA program.

Preparing for the AWA section:
To excel in the AWA section, it is essential to practice writing essays within the given time limit. Familiarize yourself with the essay prompt types and develop a structured approach to address the arguments effectively. Focus on presenting a clear thesis statement, providing logical reasoning, and supporting your ideas with relevant examples. Use proper grammar, vocabulary, and sentence structure to enhance the overall coherence and readability of your essay.

Conclusion:
While the AWA section does not directly contribute to the overall GMAT score, it holds significant importance in the admissions process. A strong performance in this section can showcase your analytical and writing skills to business schools, enhancing your chances of admission. Therefore, it is crucial to prepare well and practice writing essays to excel in this section of the GMAT exam.
