Any student registration fee or course duration extension fee once paid is not refundable.
We strongly recommend using the trial version of the course, which is free of cost, before deciding to pay the fee for student registration. This way you would be paying the fee only if you are convinced about the usefulness and worth of the course for you.
Likewise, you may decide to pay the course duration extension fee if required, only if you are convinced about the usefulness and worth of such an extension of course duration for you.
We once again reiterate that any fee paid is not refundable.
