Dear student,

As we have seen a change in cutoff for josaa, then we will get to see change in cutoff of all branches in different institutes participating in csab special round counseling.

Now, the main factor of change in cutoff for csab special round counseling, is - the number of seats vacant after josaa counseling.

So, it will be quite difficult to tell that how much there can be a change in cutoff for cse in csab special round counselling.
So, wait for the csab counselling to begin.
