How Many Marks Required to Score 90 Percentile in JEE Main: Candidates get admission to premier NITs and engineering colleges based on their percentile in the JEE Main exam. Aspirants need approximately 103-104 marks out of 300 to score in the 90th percentile in JEE Main 2026. The percentile often varies based on many factors, including the difficulty level of the test and the performance of the other candidates. The scores are calculated using the JEE Main Normalization process.
To get a 90th percentile in JEE Main, the candidate must have thorough knowledge of Physics, Chemistry, and Mathematics. Solve regular practice mock tests to improve your speed and accuracy for JEE Main.
How Many Marks Required to Score 90 Percentile in JEE Main?
Scoring 70–75 marks in JEE Main usually results in about 90 percentile. The marks differ for each session. The JEE Main percentile depends on normalization, the difficulty level, and the number of candidates who take the test. Here is an expected score range as per how many marks are required to score 90 percentile in JEE Main:
| Expected 90 Percentile in JEE Mains Rank Range | |
| Percentile | Expected Marks Range |
| 90 Percentile | 70–75 marks |
| 85–90 Percentile | 65–75 marks |
| Above 90 Percentile | 75–85 marks |
How to Calculate 90 Percentile in JEE Main?
The National Testing Agency calculates 90 percentile in JEE Main through a normalization process. It is the percentage of candidates who have scored equal to or below a particular score in a specific session. The percentile score is calculated using the formula:
Percentile = (Number of candidates who scored less than or equal to you / Total number of candidates who appeared for the exam) x 100
Scores are normalized in each session. The 90 percentile means you did better than 90% of candidates in your session.
Expected Rank Range for 90 Percentile in JEE Mains
A 90 percentile in JEE Mains usually corresponds to an approximate rank range of 1,00,000–1,50,000. This variation depends upon various factors such as the total number of candidates, session difficulty, and normalization. Here is the expected rank range for 90 Percentile in JEE Mains:
| Expected Rank Range for 90 Percentile in JEE Mains Rank | |
| Percentile | Expected Rank Range |
| 90 Percentile | 1,00,000 – 1,50,000 |
| 92 Percentile | 80,000 – 1,00,000 |
| 94 Percentile | 55,000 – 80,000 |
| 95 Percentile | 45,000 – 55,000 |
| 96 Percentile | 35,000 – 45,000 |
| 97 Percentile | 25,000 – 35,000 |
| 98 Percentile | 15,000 – 25,000 |
| 98.5 Percentile | 12,000 – 15,000 |
| 99 Percentile | 7,000 – 12,000 |
| 99.2 Percentile | 5,000 – 7,000 |
| 99.4 Percentile | 3,500 – 5,000 |
| 99.5 Percentile | 2,500 – 3,500 |
| 99.7 Percentile | 1,000 – 2,500 |
| 99.8 Percentile | 600 – 1,000 |
| 99.9 Percentile | 100 – 500 |
JEE Main Percentile vs Marks 2026
JEE Main Percentile vs Marks 2026 will help the aspirants estimate their expected percentile based on the raw marks after normalization. Since the difficulty level across shifts is different, the percentile for the same score differs. Here is the expected marks range corresponding to 90 Percentile in JEE Main:
| JEE Main Percentile vs Marks 2026 | |
| Percentile | Expected Marks Range |
| 99.9+ Percentile | 250 – 300 |
| 99.8 Percentile | 210 – 220 |
| 99.7 Percentile | 200 – 210 |
| 99.5 Percentile | 180 – 195 |
| 99 Percentile | 150 – 170 |
| 98.5 Percentile | 140 – 150 |
| 98 Percentile | 135 – 145 |
| 97 Percentile | 120 – 130 |
| 96 Percentile | 110 – 120 |
| 95 Percentile | 100 – 110 |
| 94 Percentile | 90 – 100 |
| 92 Percentile | 80 – 90 |
| 90 Percentile | 70 – 75 |
| 85 Percentile | 55 – 65 |
| 80 Percentile | 45 – 55 |
Factors Affecting JEE Main Percentile
Some key factors govern the percentile in JEE Mains. These factors ensure fairness across multiple shifts and determine how raw marks convert into percentile scores.
Some determining factors of JEE Main Percentile are given below:
1. Raw Score
The raw score or marks obtained out of 300 by the candidates is taken as the primary factor for calculating the percentile. Higher marks will generally result in a higher percentile, but the final value sometimes varies after normalization.
2. Number of Candidates in the Shift
The percentile depends on how many students obtain marks less than yours. Even a slight modification in the marks can drastically affect your percentile if more candidates sit for their examinations in your shift.
3. Difficulty Level of the Paper
Every shift of JEE Main is not equally difficult. There are often higher percentiles for the same marks in tougher papers, and easier papers require more marks to achieve a similar percentile.
4. Normalization Process
Given that JEE Main is conducted in multiple shifts, NTA attempts to bring a level of fairness between differences in difficulty levels using a normalization formula. Essentially, this adjusts the scores so that no one shift enjoys an advantage over another.
How to Score 90 Percentile in JEE Main?
Scoring 90 percentile in JEE Main requires consistent preparation, clearing your concepts thoroughly, and practicing on a regular basis with previous year papers and mock tests.
