Understand how your raw score out of 720 converts into All India Ranks (AIR). Review NTA's official percentile derivation formula, negative marking evaluation rules, and the step-by-step tie-breaking hierarchy.
NEET UG Ranks are determined by raw scores calculated as: (Correct × 4) - (Incorrect × 1). Raw marks are converted into percentile scores to establish relative merit among candidates. In case of identical raw scores, NTA resolves ties by comparing subject scores in order: **Biology, Chemistry, Physics**, followed by the candidate's proportion of wrong answers.
Verified against NTA score processing algorithms, merit list guidelines, and official candidate handbook publications.
The basic evaluation of candidate responses follows NTA's standardized marking parameters:
| Evaluation Parameter | Marking Rule & Numerical Effect |
|---|---|
| Total Questions Attempted | 180 Questions (out of 200 total provided across Section A & B) |
| Correct Response Weightage | +4 Marks per correct response |
| Incorrect Response Deduction | -1 Mark per incorrect response |
| Unattempted Questions | 0 Marks (No negative marking for unanswered items) |
| Maximum Attainable Score | 720 Raw Marks (180 × 4) |
When two or more candidates achieve the exact same raw score, NTA applies the following sequential priority rules to assign distinct ranks:
| Sequential Priority Level | Criteria & Evaluation Rule |
|---|---|
| Priority 1: Higher Biology Marks | Candidate obtaining higher raw marks/percentile in Biology (Botany + Zoology) gets the higher rank. |
| Priority 2: Higher Chemistry Marks | If Biology marks match, the candidate with higher marks/percentile in Chemistry receives preference. |
| Priority 3: Higher Physics Marks | If Chemistry marks also match, the candidate with higher marks/percentile in Physics is placed higher. |
| Priority 4: Lower Ratio of Incorrect Responses | Candidate with a lower proportion of unattempted/wrong responses across all subjects gets priority. |
| Priority 5: Subject-Wise Lower Incorrect Ratios | Sequential evaluation of lower incorrect answer ratios in Biology, followed by Chemistry, and then Physics. |
Understanding how relative performance determines your percentile standing:
Percentile indicates the percentage of total candidates who scored equal to or below your score, not your raw percentage of correct answers.
The 50th percentile for UR/EWS and 40th percentile for OBC/SC/ST define the qualifying threshold for counseling eligibility.
Unique AIRs are assigned sequentially after resolving all ties using subject performance and negative marking accuracy ratios.
Percentile = 100 × (Number of candidates who appeared in the exam with a raw score equal to or less than the candidate) / Total number of candidates who appeared.
