Ans: Most of the IIMs have preferred Written Ability Test (WAT) on Group Discussion (GD) over the last few years. Written Ability Test is designed to test a candidate’s critical thinking ability, and their ability to formulate and communicate their thoughts clearly. Candidates have to write an essay on a given topic. The time given to complete the test varies among the different IIMs. Proper practice of essay writing is the key to score well in WAT. The structure is a consideration but candidate must focus on time management too. A candidate must try to put in as many clear ideas in their essay as possible.
