See there is no reopening of the Neet application window after the deadline is over however in some cases occurs so do keep a check on the website. But since it is March and exam is in May so there might not be any chances of reopening.

Accept the situation and move on as nothing can be done now. Prepare for NEET 2026 now and be attentive next time. Or you can consider alternative exams and courses which do not require NEET.

Don't overthink and start preparing. A single year can't decide anyone's future.
