Generate supportive data

Use facts and illustrations in the Group Discussion (GD) to add value. However, be very sure of the validity of any statistic you quote. If you mention a wrong figure, someone else in the group could point out the mistake. If that doesn't happen, the evaluators might notice the mistake. A fact or a statistic cannot be an argument in itself. It can only support a point you are making. So do not quote a fact and let it land follow it up with some sort of inference or conclusion that can be drawn from it.
