Hello aspirant

hope you are doing well and safe. With reference to your query,  I would glad inform you that once application forms is filled with a category , then it is very diffcult to change at the time of csab counselling . It will remain same towards the ends of counselling as changing of category in the middle will be highly unfair to other students and can  increase competition in a particular category

Hope you found this answer informative. Best wishes for your future
