Greetings of the day aspirant !!

I am hoping that you are absolutely fine. As per your mentioned query , I would like to tell you that once you register yourself for the jee mains entrance exam then you cannot withdraw your registration and refund your money back. As per the rules , the application fees is non refundable. Once you register and pay the fees , whether you give the exam or not , you cannot get your money back. So , basically it's your choice to give your exam or not , but according to brochure of the jee mains the fees is non refundable.

I hope you are clear now.

Good luck !!
