Hey Gaurav, yes you can fill out a declaration/undertaking form in place of the EWS certificate for the NEET 2026 application process to tentatively claim the EWS category. However, you must obtain a valid EWS certificate (issued on or after April 1, 2026, for the 2026-27 session) before the counselling and admission process, or your seat may be canceled or converted to the General category.
