Once you applied and submitted the form you can't again change it and you will be not able to apply it once again also as a single student can apply only one time only , so in my knowledge there will be no other option unless you submitted it 

Hello Abhay,

Please mention the clear information. You have not mentioned that about which application form you are asking . Mention the name of the form so that it would be easy for us to help you.     

Thank you.
