There are no specific rules to prepare for a GD. And no one knows what the topic of GD is going to be. This book includes topics that are likely to be put by the Group Testing Officer before the candidates to gauge their personality and leadership qualities. It will be a good idea to keep yourself abreast with topics from:
1. Current Affairs - Current Affairs is something that you have to be thorough with. Understand the recent crises affecting the world, latest developmental initiatives, and important national & global events.
2. Historical topics- Have a fair knowledge about the history of India and the world. Having historical information will help you cite examples and make references whenever needed.
3. Sports, Arts & Literature - In these topics, try to have a decent idea about what is popular, who are the leaders in each area, the latest that has happened in these areas.
4. Data crunching - Do familiarize yourself with important data. Throwing in some data if required in your GD will definitely create an impression among the assessors.
Speak with a measure of confidence on the given topic; and secure the nod of the evaluator.
