The waitlist moved till 96 last year. Again, the waitlist movement was one of the highest in recent years. The waitlist movement has varied wildly from the lower 60s to higher 90s. One can expect the waitlist to move by at least 60.
The movement entirely depends on the overlap between the converts of IIM A, B & C.
If we talk about category wise movement, then check this
Open Category: 90–95
ST : 40–44
All the best!!
