To correct name in BITSAT form

I have submitted the BITSAT form but there is a mistake in the spelling of the name I entered so please tells me how I correct this?

[Kiran Chandar]

BITS is the Birla Institute of Technical Science

No corrections are allowed in the form. So it would be better if you purchase another form.

Otherwise there will be chances that your form will be rejected.

Or try to contact with authority as soon as possible about wrongly entered name. They will suggest you the possible way to correct your name.
If you request them I think they will change
