Dear Aspirant 

This is a very simple process that you have to carry out during admissions process. You just have to visit a bank closest to your college and just ask bank officer that you want demand draft for your admission, they will provide you a form which you have to fill in which you have to mention your account number, name, fee amount in number and words, payable at-name of your college with City pin code and state and then you will submit that form, then they will return you a cheque form paper which you have to submit at your college during admissions. 

Good luck for your admission :)

Feel free to ask if you have any further queries.
