What is JEE Main Percentile? Understanding the Basics
JEE Main Marks Explained

JEE Main marks represent your raw score in the examination. The JEE Main exam is conducted for 300 marks total, divided equally among three subjects:

  • Physics: 100 marks
  • Chemistry: 100 marks
  • Mathematics: 100 marks

Each correct answer awards +4 marks, while each incorrect answer deducts -1 mark (negative marking). Unattempted questions receive zero marks.

Example Calculation:
  • Correct answers: 60 questions = 60 × 4 = 240 marks
  • Incorrect answers: 10 questions = 10 × 1 = -10 marks
  • Total Score: 230 marks out of 300
What is JEE Main Percentile?

JEE Main percentile is NOT the same as percentage. A percentile score indicates your relative performance compared to all other candidates who appeared in your examination session. It represents the percentage of candidates who scored equal to or below your score.

Percentile Calculation Formula:
Example:

If you scored 180 marks and 10 lakh students appeared for JEE Main:

  • Candidates scoring ≤ 180 marks: 9,50,000 students
  • Your percentile = (9,50,000 / 10,00,000) × 100 = 95 percentile

This means you performed better than 95% of all candidates

JEE Main Rank: The Final Merit Position

Your All India Rank (AIR) is derived from your percentile score, not directly from raw marks. After normalization across all sessions, NTA prepares the final merit list based on percentile scores. Higher percentile = Better rank = Higher chances of admission to top NITs and IITs.

Key Insight: A 99.9 percentile typically corresponds to top 1,000-1,500 ranks, while a 99 percentile translates to approximately 8,000-10,000 rank range.

Expert Tip: For admission to top NITs in popular branches like Computer Science, you typically need 99+ percentile (under 10,000 rank). For state-level engineering colleges, 85-90 percentile is generally sufficient.

Subject-Wise Marks vs Percentile Breakdown 2025

Understanding subject-wise performance is crucial as NTA calculates separate percentiles for Physics, Chemistry, and Mathematics. These individual subject percentiles don't directly affect your rank but provide insights into your strengths.

Physics Marks vs Percentile (Out of 100)
Physics MarksExpected Percentile
95-10099.5+
90-9499.0 - 99.4

50-5472.0 - 78.4

Key Observation: Mathematics typically has the widest score distribution, making it the most differentiating subject for top rankers. Chemistry often has the highest average percentiles.

Shift-Wise JEE Main 2025 Marks vs Percentile Analysis

JEE Main 2025 is conducted in multiple shifts across different days. The difficulty level varies slightly between shifts, which is why NTA implements normalization. Here's the expected variation:

January Session 2025 - Shift-wise Expected Marks for 99 Percentile
DateShift 1Shift 2
Day 1190-195 marks185-190 marks
Day 2192-197 marks188-193 marks
Day 3187-192 marks183-188 marks
Day 4193-198 marks189-194 marks
April Session 2025 - Shift-wise Expected Marks for 99 Percentile
DateShift 1Shift 2
Day 1188-193 marks184-189 marks
Day 2191-196 marks187-192 marks
Day 3185-190 marks181-186 marks
Day 4194-199 marks190-195 marks

Important Note: These are expected ranges. Actual normalization is done by NTA after considering the performance distribution of all students in each shift. Generally, Shift 2 papers are slightly tougher than Shift 1.

Historical Comparison: JEE Main Marks vs Percentile (2022-2024)

Learning from past trends helps set realistic expectations. Here's how the marks vs percentile relationship has evolved:

Year-wise Comparison for Key Percentiles
Percentile2024 Marks2023 Marks2022 Marks
99.9+260-270265-275262-272
99.5+230-240235-245232-242
99.0+190-200195-205192-202
98.0+160-170165-175162-172
97.0+140-150145-155142-152
95.0+115-125120-130117-127
90.0+85-9590-10087-97
Trend Analysis:
  • 2023 papers were slightly tougher than 2022, requiring 3-5 more marks for the same percentile
  • 2024 saw normalization with difficulty returning to 2022 levels
  • 2025 is expected to maintain similar difficulty as 2024
Category-Wise JEE Main Cutoff Percentile 2025

NTA sets qualifying percentiles for different categories to determine JEE Advanced eligibility:

JEE Main Qualifying Percentile by Category

What This Means: You need to score above these percentiles to qualify for JEE Advanced (for IIT admissions) and be eligible for NITs/IIITs through JoSAA counseling.

How is JEE Main Percentile Calculated? Understanding Normalization

Since JEE Main is conducted in multiple sessions with different difficulty levels, NTA uses
