Commonly asked questions

Q: Can I edit my CAT application form after submission?

Once the CAT application form is submitted, candidates are not allowed to make changes in it. In case, you've made errors, you need to fill a fresh CAT application form and pay the fees again. However, editing of certain fields such as photo, signature and test city preference is allowed during form correction process which starts 2-3 days after the CAT registration process concludes. The form correction window is opened for 3-4 days during which candidates can edit only these three fields. If they have made a mistake in any other field, they cannot edit it. No request for changes is accepted by the examination authorities. Thus, it is very important to fill the CAT application form correctly with valid details. Candidates must keep the important documents such as Aadhaar card, class 10, class 12, graduation certificates, birth Certificate address proof, work experience documents, etc. To cross check the information while filling the form.

The registration and application window will remain open for candidates who have registered for the exam and created an ID until the last date of form submission.
