When you approach this issue analytically, it becomes surprisingly simple to comprehend. Here are a few of the best colleges along with an estimated number of seats overall. IIM Ahmedabad - More than 400 IIM Bangalore - More than 400 IIM Calcutta - More than 400 IIM Lucknow - More than 400 XLRI - Around 360 FMS - Approximately 200 SP Jain - Around 240 There are more than 2400 seats available if you only take the aforementioned colleges into account, and most students who are converting to those institutions will likely choose them over Kozhikode or Indore. The majority of those on the first list who convert also receive calls from these colleges, which convert them. As a result, there is a significant overlap of candidates, which causes Indore and Kozikode to move up the waitlist quickly. Please keep in mind that the number of buffer calls made also affects how far along the waitlist a person is. Maybe the high waitlist movement is being caused by I and K making fewer buffer calls.
