What is the right time to enter a GD to ensure that I am heard properly?
In any GD, there are crests and troughs during the discussion. The crest is when the noise level is at its peak. The trough is when there is almost total silence. Ideally, you should enter the GD during the trough period. But in competitive GDs, the crests occur more often and troughs may not occur at all. In such cases, you could identify the stages in the GD, where ideas dear to you are being discussed and enter the GD irrespective of the noise level.
