I have put together a compilation of articles on various topics of interest that might turn up in this year’s WAT-GD-PI season. Don’t speed-read these articles and make notes solely from a point of view of WAT-GD, as if you were preparing essay type answers on topics for a test in school. The narrower you go, the deeper the hole you dig yourself into.
The IIM-A process involves an AWT as opposed to the WAT. The best way to understand the difference is to view the two as the two essays that the GMAT had earlier – Analysis of an Issue and Analysis of an Argument.
