How is the percentile in JEE Mains calculated?

<p data-sourcepos="1:1-1:187">The percentile score in JEE Mains is calculated based on the relative performance of all the candidates who appeared for the exam in a specific session. Here's a breakdown of the process:</p><p data-sourcepos="3:1-3:27"><strong>1. Score Normalization:</strong></p><p data-sourcepos="5:1-5:457">JEE Main scores are normalized to account for the varying difficulty level of the exam across different sessions. Normalization aims to create a level playing field for candidates appearing in different sessions. The exact method of normalization is not publicly disclosed by the National Testing Agency (NTA), but it likely involves statistical techniques to adjust raw scores based on factors like the average score and standard deviation in each session.</p><p data-sourcepos="7:1-7:30"><strong>2. Percentile Calculation:</strong></p><p data-sourcepos="9:1-9:112">Once the raw scores are normalized, the percentile for each candidate is calculated using the following formula:</p><p data-sourcepos="11:1-11:120"><strong>Percentile = (100 x Number of Candidates with equal or lower normalized score) / Total Number of Candidates Appeared</strong></p><p data-sourcepos="13:1-13:41"><strong>Here's an explanation of the formula:</strong></p><ul data-sourcepos="15:1-18:0"><li data-sourcepos="15:1-15:65"><strong>100:</strong>&nbsp;This represents the total percentile range (0 to 100).</li><li data-sourcepos="16:1-16:194"><strong>Number of Candidates with equal or lower normalized score:</strong>&nbsp;This refers to the number of candidates who scored the same or less than the candidate in question on the normalized score scale.</li><li data-sourcepos="17:1-18:0"><strong>Total Number of Candidates Appeared:</strong>&nbsp;This is the total number of candidates who appeared for the JEE Mains exam in that specific session.</li></ul><p data-sourcepos="19:1-19:248">For example, if a candidate scores 150 marks and there are 1000 candidates who scored 150 or less (including the candidate themselves), and the total number of candidates who appeared for the exam is 10000, then the candidate's percentile would be:</p><p data-sourcepos="21:1-21:43"><strong>Percentile = (100 x 1000) / 10000 = 10%</strong></p>
