A. In case your test does not gets uploaded or certified due to a technical problam, you can take the test again without paying an additional fee. But you should have attempts remaining in the credit. If the identity proof which you submitted is problematic you will have to submit a valid ID again in order to get your results. You don't need to appear for the entire test again.
