i want cancel my application form which I applied for jee main because i am not interested to join engineering

Dear student,

If you have filled the form and have submitted it and your confirmation page is generated, so now, you cannot cancel your application and take a refund of your application fees.

But if you are not interested in engineering, then you can do one thing - don't give the jee mains exam. And turn your path from engineering to any field of your interest.

And always take decision and choose path wisely.
