Hi there! Thanks for reaching out to us at Careers360 about your CBSE exam situation.

Oh no, filling out the wrong form can be such a headache! Don't worry though, we'll try to sort this out.

For cancelling an improvement exam registration with CBSE, you'll want to contact your school or the CBSE regional office directly as soon as possible. They're the ones who can help process cancellation requests.

I'd suggest speaking with your school counsellor or principal first, as they often have the most up-to-date info on CBSE procedures. If you need to go directly to CBSE, you can find contact details for your regional office on the official CBSE website.

Just remember, there might be a deadline for cancellations, so it's best to act quickly. Do you need any help finding the right contact information?
