NEW DELHI: One in every three candidates registered for the June 21 NEET-UG re-exam come from just three states — Uttar Pradesh, Maharashtra and Rajasthan — according to data from National Testing Agency (NTA).NEET-UG — involving more than 22.7 lakh medical aspirants — is the single-largest national entrance test of the country. It is the gateway to nearly all UG medical seats, with students competing every year for limited places. The retest was necessitated due to the cancellation of the May 3 exam due to the question paper being leaked.UP alone accounts for 3,56,291 candidates, or 15.7% of the total — the largest share of any state or UT.
