What happens in IIM Calcutta if your percentage is less than the percentage mentioned in your CAT form?

Any IIM will do the following if your score is lower or higher than what you indicated on the CAT form: It will be changed if the score is higher, but you must first fill out a form, and the higher percentage will be considered for further selection consideration.

If it is less than what you specified on the CAT form, they will inquire as to why. After hearing your reason, they will change back to the actual percentage by filling out the form with your signature. If it happened by mistake, there will be no problem.
