Dear applicant whenever you plan to leave any course, you always have the access to withdraw your admission. But yes the refund of the fees that you already paid, totally depends on the refund policy of the Institute. Most often any reputed institution will refund the money that you already paid, may be they will not return the total amount only 5% will be deducted. So you apply for refund, send a mail stating your withdrawal issues, and ask for all the details that you need to submit to enable the return.

Good luck!!
