All applicants need to pay an application fee. It's Rs. 5000/- for most candidates, but if you're from the SC/ST category in Rajasthan, it's Rs. 2500/-. Along with this fee, there are some charges from the bank or your card company that you'll need to cover.

You'll pay this fee online while filling out the application form. You can use a Credit or Debit Card, Internet Banking, or UPI for this. Remember, you can't pay with cash or cheque, only online.

Once you've paid the fee during the application process, you won't need to pay again. But, it's important to know that this fee can't be returned to you, even if you decide not to go through with the application later on. Also, you can't transfer this fee to another application.

If, for any reason, you're unable to attend the exam or if you're found to be ineligible later on, you won't get your fee back. So, it's essential to make sure you're eligible and available for the exam before you apply.
