The qualifying marks for NEET UG are determined based on percentile rather than a fixed score. Candidates in the General category must score at least the 50th percentile to qualify for the exam. For candidates belonging to SC, ST, and OBC categories, the qualifying percentile is 40th. For General-PwD candidates, the qualifying percentile is 45th. The actual marks corresponding to these percentiles vary each year depending on exam difficulty and candidate performance. Only candidates who meet the qualifying percentile are eligible to participate in the counseling process.
