CBSE Grading System — Positional Grades, CGPA & Percentage Explained

CBSE grades Class 10 and Class 12 board exams by position, not by fixed marks. In each subject, the students who passed are ranked and split into eight equal groups: the top 1/8th get A1, the next 1/8th A2, and so on down to D2. Students who do not pass get E (Essential Repeat). There are no grade points and no CGPA on current marksheets. The CGPA × 9.5 rule only applies to old CGPA marksheets.

That's the short version. If you're a student trying to work out what your grade means, or a parent wondering whether a B1 is good enough for admissions, this guide explains how CBSE grading works, what your marksheet actually shows, and when CGPA still matters.

The Grades CBSE Awards in Board Exams

CBSE gives one of nine grades in each subject. The first eight are awarded by rank among students who passed that subject. Here is the scale from the CBSE curriculum:

There are no marks ranges or grade points in this table, and that is deliberate: the marks needed for each grade depend on how everyone scored that year. To pass a subject you need at least 33%.

How Positional Grading Works

After all answer books in a subject are evaluated, CBSE takes every student who passed and ranks them from highest to lowest. Then it divides them into eight equal groups, from A1 at the top to D2 at the bottom. Students who did not pass are not part of this ranking; they get E.

In practice, if a paper was tough and scores were lower overall, the marks needed for A1 drop. If the paper was easy and scores were high, you need more marks to land in the top 1/8th. Two students with the same marks in different years can therefore get different grades. CBSE adjusts slightly for ties (students with the same score get the same grade), and in small subjects with fewer than 500 passed candidates it follows the pattern of similar subjects.

What Your Marksheet Shows

• Marks for each subject — theory, internal assessment or practical, and the total.
• The positional grade for each subject.
• No aggregate. CBSE does not declare an overall percentage, division, distinction or merit list. When a college needs a percentage, it calculates one by its own rules from your subject marks.

If you fail a main subject but pass an additional subject, CBSE can replace the failed one. In Class 10, a skill subject taken as the 6th subject replaces a failed Science, Maths or Social Science. In Class 12, the 6th subject can replace a failed main subject as long as English or Hindi stays among your five main subjects.

Class 9 and Class 11: Fixed Marks Bands

The familiar "91–100 = A1" table is real, but it is the school-level scale for Class 9 and Class 11, where schools grade their own exams. CBSE uses absolute grading there because a single school has too few students for positional grading.

Old CGPA Marksheets: CGPA to Percentage

Older CBSE Class 10 marksheets from the CCE scheme show a CGPA instead of marks. For those, the conversion is:

Percentage = CGPA × 9.5

So a CGPA of 8.8 converts to 8.8 × 9.5 = 83.6%. It is an indicative figure, not your exact marks. Current marksheets already show marks, so you don't need this unless you are working with an old certificate. You can also use our CGPA to percentage calculator or read the CGPA to percentage guide.

How Grades Affect College Admissions

Admissions run on marks, not grades. For CUET-based admissions (Delhi University, JNU, BHU and other central universities), your CUET score is the main criterion and board marks are usually a minimum eligibility condition.

For state-level and private college admissions, many institutions look at your board marks directly and work out a percentage by their own rules.

For JEE and NEET, you must meet the Class 12 eligibility conditions in that year's information bulletin. For example, admission to NITs, IIITs and other centrally funded institutes through JoSAA needs at least 75% in Class 12 (65% for SC/ST) or a place in the top 20 percentile of your board. Beyond eligibility, your entrance score decides. See the CBSE Class 12 exam pattern to plan your board preparation.

How Marks Are Split: Board Exam, Internal Assessment and Practicals

• Class 10, most subjects: 80 marks board exam + 20 marks internal assessment. The 20 marks are Periodic Assessment 5, Multiple Assessment 5, Portfolio 5 and Subject Enrichment 5, all assessed by your school.
• Class 10 Science: 80 theory + 20 internal assessment; practical work is part of the internal assessment. Computer Applications is 50 theory + 50 practical.
• Class 12: Physics, Chemistry, Biology, Computer Science and several other subjects are 70 theory + 30 practical. Subjects such as Accountancy, Business Studies, Economics, History and Political Science are 80 theory + 20 project.

Internal, practical and project marks are part of your subject total, so they move your rank within the subject and therefore your grade.

Tips to Improve Your Grade

1. Don't neglect any subject. Every subject gets its own grade, and colleges see each subject's marks.
2. Take internal assessment seriously. The 20 internal marks in Class 10 (and practical or project marks in Class 12) are largely in your control: periodic tests, activities, your portfolio and subject enrichment work all count.
3. Study NCERT thoroughly. NCERT textbooks are the prescribed books for CBSE, and board questions are built on them. See the Class 10 and Class 12 exam patterns for how papers are set.
4. Practise previous year and sample papers. They show the question types, the level of detail expected, and how marks are split in the marking scheme.
5. Focus on presentation. Use headings, points, labelled diagrams and underlined key terms so the examiner can find each marking point quickly.
6. Remember that grades are relative. A tough paper is tough for everyone. Staying calm and attempting every question protects your rank.
7. Don't skip practicals. In Class 12 science subjects the practical exam is 30 of the 100 marks.

What Changed in 2026?

The grading method is unchanged: positional grades A1 to D2 and E (Essential Repeat). What changed in 2026 was the two-exam system for Class 10 (main exam 17 February–11 March 2026, optional second exam 15–21 May 2026, better of the two counts), and Class 12 answer books were evaluated fully by on-screen marking.

The Bottom Line

CBSE board grades tell you where you stand among everyone who passed a subject that year. Your marks are what colleges use, and CBSE does not add them up into a percentage for you. CGPA only matters if you hold an old CGPA marksheet, and then CGPA × 9.5 gives an indicative percentage.

What matters most is consistent preparation, strong NCERT fundamentals, and not leaving easy marks on the table in internal assessment and practicals.
