NEET and AIIMS Entrance Exam: An OverviewNEET is a national-level entrance examination for students seeking admission to medical courses in India. It is mandatory for admission to MBBS, BDS, and other undergraduate medical programmes across government and private colleges.The AIIMS Entrance Exam was previously conducted separately for admission to MBBS programmes at AIIMS institutions. However, since 2020, admissions to AIIMS have been based solely on NEET scores. As a result, NEET has become the single entrance examination for almost all medical admissions in India. NEET (National Eligibility cum Entrance Test)NEET is conducted once a year and serves as the primary medical entrance examination in India. Candidates must qualify in NEET to secure admission to undergraduate medical courses in recognised institutions. AIIMS Entrance Exam (Before 2019)Before 2019, AIIMS conducted its own entrance examination for MBBS admissions. From 2020 onwards, AIIMS admissions have been merged with NEET, making NEET scores the basis for selection.This change has made NEET the most important examination for medical aspirants, as it determines admission to nearly all medical colleges, including AIIMS.
