Understanding Percentile vs. Rank ๐Ÿ—“

Whatโ€™s the Difference?

Many students confuse percentile with rank, but theyโ€™re not the same. Your percentile tells you the percentage of candidates who scored less than you, while your rank is your position relative to all test-takers.

For example, if you score in the 95th percentile, it means youโ€™ve outperformed 95% of the candidates. However, your rank could still be in the hundreds or thousands, depending on the total number of applicants.

Step-by-Step Guide

Calculating your AIIMS MBBS percentile involves a few straightforward steps. Hereโ€™s how it works:

StepDescription
Step 1: Raw ScoreCalculate your total correct answers minus incorrect ones (if negative marking applies).
Step 2: NormalizationAdjust your score based on difficulty levels across different exam sessions.
Step 3: Percentile FormulaUse the formula: Percentile = (Number of candidates who scored less than you / Total number of candidates) x 100.
Step 4: Final PercentileRound off the result to two decimal places for accuracy.

Real-Life Example

Letโ€™s say 10,000 candidates appeared for the exam, and 8,500 scored less than you. Using the formula:

Percentile = (8,500 / 10,000) x 100 = 85%

This means youโ€™re in the 85th percentile, outperforming 85% of the candidates.
