If you’ve already submitted the Kanpur University (CSJMU) application and realize you made a mistake like using the wrong email you cannot edit the form after final submission because there’s no correction window available . This means you’re locked into whatever information you initially provided. To fix it, you’ll need to re-register completely, using a new email and phone number that are both correct   Make sure to follow the official entrance instructions provided by the university for registration details If there’s a small type and you haven’t submitted yet, you might be able to log in and correct it until the final submission. After that point, the only option remaining is to start over. So yes, you can re-register, but only as a brand new application with fresh contact details.
