Dear student.

If there are vacant seats then those seats are filled in spot/special round counselling. Internal sliding is allowed in government colleges which means that a candidate can change his/her branch within the same college if there are vacant seats in that particular branch. It is subjected to vacancy and merit.

So, It purely depends upon your rank and the vacant seats only. Vacant seats will be displayed on 26 november and student who has good rank might get that seat. You can try if you have good rank.

Hope it Helps!
