The essence of GD is how to focused on theme of the subject and then conclude. Let us discuss a topic like FDI in retail would be good or not ?
Over here we need not discuss the political differences of different parties and thereon politics of convenience. We need not refer to any comments of any party.
We need to emphasise on FDI only and if possible we can start with the history of FDI and then Kirana stores and consumer behavior in relation to Pop N’ Mom Stores.
The more we focus on the topic automatically you would be able to talk logical and you will conclude also logically.
You need to practice on variety of topics for GD so that you are successful.
