Hello Pooja,

As per the official, It will be mandatory for candidate to furnish, at the time of admission in the concerned Colleges a bond, on Rs. 100/- stamp paper. The undertaking/bond is to ensure that in case the student leaves the seat after the 2nd/final counseling, or at any time during the course of study, leading to a loss of the seat, then the candidate will deposit an amount of Rs 5,00,000. You can check the complete information about it with the given below link on Page No. 6.
