Understanding Marksheet Grading Systems & Percentile Calculations
Board exam results are an important turning point for every student in India. But once the result is declared, one of the most common confusions students face is: “What do these grades mean?”, “How is percentile different from percentage?”, or “Why didn’t I get exact marks?”.
The education system in India has been evolving, and in 2025, most school boards and entrance exams have adopted modern evaluation tools like grading systems, percentile scores, and normalization. This guide will help you understand how your performance is assessed, why these methods are used, and how you can interpret your results effectively.
Whether you’re a Class 10 or 12 student, a parent, or preparing for competitive exams like JEE or NEET, understanding these terms will empower you to make smart academic decisions.
🔢 What is a Grading System?
By using grades rather than just raw scores, a grading system provides a way to assess a student’s academic performance. It standardizes results and reduces stress caused by minor mark differences.
✅ Example of a Standard Grading Pattern:
| Grade | Marks Range | Performance |
|---|---|---|
| A1 | 91% – 100% | Outstanding |
| A2 | 81% – 90% | Excellent |
| B1 | 71% – 80% | Very Good |
| B2 | 61% – 70% | Good |
| C1 | 51% – 60% | Above Average |
| C2 | 41% – 50% | Average |
| D | 33% – 40% | Below Average |
| E | Below 33% | Fail |
🔍 Key Point: Two students with 93 and 97 marks both get A1. This avoids unnecessary stress over a few marks.

🎯 Why Are Grading Systems Used?
Boards have adopted grading systems for multiple practical and psychological reasons:
- Standardization Across Schools/States: Different exam papers have different difficulty levels. Grades help normalize that.
- Less Stress: Students don’t worry about getting one or two marks more.
- Focus on Learning: Encourages deeper understanding, not rote learning.
- Equity in Evaluation: Levels the playing field for students from different backgrounds.
🇮🇳 Common Grading Systems Used by Indian Boards
Each education board in India uses its own version of a grading system. Here are some major examples:
🔷 CBSE Grading System (Central Board of Secondary Education):
CBSE does not reveal exact marks for subjects but provides grades. The overall CGPA (Cumulative Grade Point Average) is calculated for Class 10.
| Grade | Marks Range | Grade Point |
|---|---|---|
| A1 | 91–100 | 10.0 |
| A2 | 81–90 | 9.0 |
| B1 | 71–80 | 8.0 |
| B2 | 61–70 | 7.0 |
| C1 | 51–60 | 6.0 |
| C2 | 41–50 | 5.0 |
| D | 33–40 | 4.0 |
| E1/E2 | Below 33 | Fail |
🟢 State Board Variations:
Most state boards like those in Uttar Pradesh, Rajasthan, Bihar, and Maharashtra follow similar patterns but may disclose exact marks along with grades.
Always refer to your specific board’s official guidelines.
📈 What is Percentile Calculation?
A percentile indicates your relative performance among all the candidates who appeared for an exam.
👉 For example, if your percentile is 85, it means you performed better than 85% of students.
This system is widely used in competitive exams like:
- JEE Main / JEE Advanced
- NEET
- CUET
- State CET exams
📊 How to Calculate Percentile Score
🧮 Basic Percentile Formula:
Percentile=(Number of students scoring below youTotal number of students)×100\text{Percentile} = \left( \frac{\text{Number of students scoring below you}}{\text{Total number of students}} \right) \times 100Percentile=(Total number of studentsNumber of students scoring below you)×100
✅ Example:
- Total candidates: 10,000
- Candidates scoring below you: 8,500
Percentile=(850010000)×100=85\text{Percentile} = \left( \frac{8500}{10000} \right) \times 100 = 85Percentile=(100008500)×100=85
Your percentile is 85.
🆚 Percentage vs Percentile – What’s the Difference?
| Factor | Percentage | Percentile |
|---|---|---|
| Definition | Marks out of 100 | Performance relative to peers |
| Formula | (Marks / Total Marks) × 100 | (Below You / Total Candidates) × 100 |
| Focus Area | Individual performance | Comparative ranking |
| Usage | Academic report cards | Competitive exams & normalization |
| Example | 75% = 75 marks in 100 | 90 percentile = Top 10% students |
📚 Why Percentile Scores Matter in 2025
- 🏫 Used in Admissions: Colleges consider percentile ranks to decide cut-offs.
- ⚖️ Fair Comparison: Eliminates difficulty variation in exam papers.
- 🌐 National Benchmarks: Allows national-level comparison across diverse student populations.
🔄 What is Normalization?
In exams conducted in multiple sessions (like JEE Main), the difficulty level may vary from one session to another. Normalization adjusts marks to ensure fairness.
🎓 Used By:
- CBSE
- NTA (JEE, NEET, CUET)
- State-level CETs
🔍 Key Benefit: Students aren’t penalized for getting a tougher paper.

⚠️ Common Mistakes Students Make
❌ Confusing Percentage with Percentile
These are not interchangeable terms and should not be mixed up.
❌ Ignoring Board-Specific Guidelines
Always check your respective board’s result interpretation methods.
❌ Misunderstanding Grades as Marks
A grade range means marks could be anywhere within that bracket.
❓ Frequently Asked Questions (FAQs)
Q1: Are grades better than marks?
🟢 Grades simplify evaluation, but marks give exact performance. Both are important.
Q2: Why do I see percentile in JEE but not CBSE?
🟢 Percentile is common in competitive entrance exams, while school boards usually report marks/grades.
Q3: Can I improve my percentile via rechecking?
🟢 Yes. If your score improves after revaluation, your percentile may go up.
Q4: good percentile is a for JEE?
🟢 Above 90 percentile is generally considered good. Above 98 is ideal for top colleges.
