How do I calculate my marks from percentiles?

You can't directly calculate your exact marks (raw score) from percentiles alone; percentiles tell you your rank (e.g., 75th percentile means you scored better than 75% of others). To find your score from a percentile, you need the mean (average) and standard deviation (spread) of the scores, then use a z-score formula ( 𝑥 = z * SD + Mean 𝑥 = z * S D + M e a n ) or an inverse normal calculator to find the corresponding score, as percentiles show relative performance, not absolute points.

How to calculate marks from percentiles?

NEET Percentile

Raw score obtained by adding and subtracting marks based on answers. Rank-based measure showing percentage of candidates scored below or equal to you. Calculated by: (Correct answers × 4) – (Incorrect answers × 1). Calculated using: ((Total candidates – Your rank) / Total candidates) × 100.
