The Written Ability Test (WAT) is a short essay-writing exercise conducted during the selection process after CAT results. Candidates are given a topic related to current affairs, business, social issues, or abstract themes and are required to write a structured essay within a limited time (usually 15–30 minutes). WAT assesses clarity of thought, logical reasoning, communication skills, and awareness of current events. Performance in WAT carries specific weightage in the final composite score.
