Marking Scheme: Each correct answer awards +4 marks. Each incorrect answer deducts -1 mark. Unattempted questions receive no marks.
Raw Score Calculation: The JEE Main marks can be calculated using the formula: JEE Main Marks = (4 × Correct Answers) − (1 × Incorrect Answers).
Percentile Score: Percentile reflects a candidate’s performance relative to others in the same session. It is calculated on a scale from 0 to 100 using score normalisation to account for varying difficulty across sessions.
Normalization Process: Scores are normalised for each session to ensure fairness. The highest raw score in each session corresponds to a percentile of 100.
NTA Score Compilation: Percentile scores for all sessions are merged to calculate the final NTA score, which determines the overall rank.
Rank Prediction: Ranks are derived from percentile scores. For example, a percentile of 99.88-99.91 corresponds to a rank of 800-1000, while >99.99 percentile is typically within the top 100 ranks.
Session-Specific Percentiles: Separate percentiles are calculated for subjects like Mathematics, Physics, and Chemistry, and then combined for the total score.
Tie-Breaking Criteria: Higher percentile in Mathematics > Physics > Chemistry is prioritised. If still tied, older candidates are ranked higher.
