The National Testing Agency (NTA) has recently provided an in-depth analysis regarding the scoring system used in the JEE Mains Session 2 exam. This analysis, shared on their official social media platforms, sheds light on how percentile scores and raw marks are determined in this highly competitive examination.
According to the data released by NTA, the marks necessary to achieve the 99th percentile varied significantly across different shifts of the exam. Specifically, candidates needed to score 165 marks in the most challenging shift, while those in the easiest shift required 196 marks. This discrepancy of 31 marks out of a total of 300 highlights the inherent variability in exam difficulty.
For the 98th percentile, the variation was slightly less pronounced, with a difference of 27 marks, while the 97th percentile saw a variation of 26 marks. Such differences underscore the complexities involved in assessing performance across multiple exam sessions.
Perfect Scores and Their Rarity
Interestingly, the NTA reported that only two shifts managed to record a perfect score of 300. In another instance, a score of 285 marks was enough to secure the 100th percentile, marking it as the highest score achieved during that session. This information is crucial for students aiming for top ranks, as it indicates the competitive nature of the exam.
Understanding Score Variations
The NTA emphasized that variations in scores across different shifts are not uncommon in large-scale examinations. Despite implementing multiple layers of moderation and calibration, it is acknowledged that the difficulty of question papers cannot be uniformly identical. This means that students taking the exam on different days may face varying levels of challenge.
To ensure fairness, the NTA explained that the percentile score is designed to reflect a candidate's performance relative to others who took the exam in the same shift. A percentile score indicates the percentage of candidates that a student has outperformed within that particular session, allowing for a more equitable assessment.
The Normalization Process Explained
One of the key points made by the NTA is the importance of the normalization process in creating a common merit list. Raw marks alone cannot be utilized for this purpose due to the potential disadvantages faced by candidates who sit for tougher shifts. Instead, the NTA employs a normalization process where percentile scores are calculated for each shift and then amalgamated to form the final rankings.
This approach ensures that candidates achieving similar percentiles across different shifts are treated equally, regardless of the differences in their raw scores. This method is crucial for maintaining fairness in the evaluation process, especially in a competitive environment like the JEE Mains.

Implications for Students
For students preparing for the JEE Mains, understanding the percentile system is crucial. It highlights the need for strategic preparation, as performance can vary significantly depending on the shift. Students should aim to achieve a score that not only meets the minimum requirements for their desired percentile but also positions them competitively against their peers.
Moreover, the normalization process assures students that their scores are evaluated fairly, regardless of the exam's difficulty level on their test day. This transparency can alleviate some of the pressures associated with the exam, allowing students to focus on their preparation without undue concern over the variability of the test.
