JEE Main 2026: Marks vs. Percentiles

Overview of JEE Main 2026: The JEE Main 2026 Session 2 examination is currently taking place, with the final exams set to conclude tomorrow, April 8th. Results will be announced shortly after. A common query among students is: "Why do I have a low percentile despite decent marks?" or "How can I achieve a 90+ percentile with a low score?" It's essential to note that the JEE Main results are influenced by the overall performance of all candidates nationwide, making it vital to differentiate between marks and percentiles.

**Defining Marks:**
In the context of JEE Main, your 'Marks' or 'Raw Score' refers to the numerical value you receive after completing the exam. This score is calculated based on the number of correct and incorrect answers. For each correct answer, you earn 4 points, while 1 point is deducted for each incorrect response. Thus, your total score reflects your individual performance in the exam.

**Understanding Percentiles:**
A percentile measures your performance relative to your peers. For instance, achieving a 90th percentile means you performed better than 90% of the candidates who took the exam. This metric does not indicate your absolute score but rather your standing within the overall merit list. Therefore, percentiles are crucial in JEE Main, as they primarily determine your All India Rank (AIR).

**Key Differences Between Marks and Percentiles:**

Marks and percentiles are fundamentally different. Marks denote your exact numerical score, while a percentile reflects how your performance compares to others. This explains why a student might have a high score but a low percentile, or vice versa.

**Achieving a 90+ Percentile with Low Marks:**
It is feasible to attain a 90+ percentile even with a lower score due to the 'Normalization System.' The exam is conducted in multiple shifts, and the difficulty level can vary significantly. The NTA uses normalization to ensure fairness across all shifts. If you took the exam during a tougher shift, your percentile could be higher despite a lower raw score.

**Reasons for Low Percentiles Despite High Marks:**
Your percentile is influenced by the performance of your peers. If most students in your shift scored poorly, your percentile will increase. Conversely, if many students scored well, your percentile may decrease. Thus, your percentile is not solely a reflection of your efforts but also of others' performances.

**Impact of Small Score Differences on Ranks:**
With millions participating in JEE Main, competition is fierce. A mere 2 or 3 marks can result in thousands of rank differences. This highlights the importance of not just answering many questions but also ensuring accuracy and minimizing negative marking.
