CBSE Class 10 Marking Scheme 2026 — Subject-Wise Marks

CBSE Class 10 board exams are marked out of 100 per subject — 80 marks theory + 20 marks internal assessment. Examiners follow a strict step-wise marking scheme. Knowing how marks are awarded can add 10–15 marks to your score.

Subject-Wise Marks Distribution

Subject	Theory (Board Exam)	Internal Assessment	Total
Mathematics	80	20	100
Science	80	20	100
Social Science	80	20	100
English	80	20	100
Hindi / Second Language	80	20	100

Internal Assessment Breakdown (20 Marks)

Component	Marks	What It Covers
Periodic Tests	10	Best of 3 tests conducted during the academic year
Notebook Submission	5	Completeness, neatness, regularity of classwork and homework
Subject Enrichment	5	Lab work (Science), speaking & listening (English), projects (Maths/SST)

How Step Marking Works — With Examples

CBSE examiners do not just check the final answer. Each step has marks allocated independently.

Maths — 3-Mark Question Example

Step	What Examiner Checks	Marks
1	Correct formula written	1
2	Correct substitution of values	1
3	Correct final answer with units	1

If you write the correct formula and substitute correctly but make a calculation error, you still get 2 out of 3 marks.

Science — 5-Mark Question Example

Step	What Examiner Checks	Marks
1	Definition or concept stated	1
2	Diagram drawn	1
3	Diagram labelled correctly	1
4	Explanation with examples	1
5	Application or conclusion	1

Common Mistakes That Cost Marks

Mistake	Marks Lost	How to Avoid
Not writing the formula before solving	1 mark per question	Always write the formula first, then substitute
Missing units (cm, m, kg, N)	0.5–1 mark per question	Write units at every step and in the final answer
Unlabelled diagrams	1–2 marks per diagram	Label all parts immediately after drawing
Paragraph answers for list questions	1–2 marks (examiner misses points)	Use bullet points or numbered lists
Leaving questions blank	Full marks for that question	Always attempt — partial answers earn step marks
Not balancing chemical equations	1 mark per equation	Count atoms on both sides before writing the answer

Tips to Maximise Marks in Each Subject

Mathematics

Show every step — formula, substitution, calculation, answer
Draw figures for geometry questions even if not asked
Write "Given", "To Find", "Solution" for word problems
Verify answers by substituting back where possible

Science

Draw and label diagrams for every relevant question
Write balanced chemical equations with states (s, l, g, aq)
Include conditions above the arrow (heat, catalyst, pressure)
For numericals: formula → substitution → answer with units

Social Science

Use dates, names, and specific facts — not vague statements
For map questions, mark neatly and label clearly
Answer in points, not paragraphs — examiners scan for keywords
Include examples for "explain" and "discuss" questions

English

Follow the word limit — examiners do not give extra marks for longer answers
Use the format for letters, notices, and articles (marks allocated for format)
For reading comprehension, answer in your own words — do not copy the passage
Grammar questions have one correct answer — no partial marks

Frequently Asked Questions

Do CBSE Class 10 examiners give step marks?

Yes. CBSE has a detailed marking scheme where each step in a solution carries specific marks. For a 3-mark Maths question: formula = 1 mark, substitution = 1 mark, final answer with units = 1 mark. Even if the final answer is wrong, correct intermediate steps earn marks independently.

How is CBSE Class 10 internal assessment calculated?

Internal assessment (20 marks per subject) consists of: Periodic Tests — 10 marks (best of 3 tests conducted during the year), Notebook Submission — 5 marks (completeness, neatness, regularity), and Subject Enrichment Activity — 5 marks (lab work for Science, speaking/listening for English, projects for Maths/SST). Schools submit these marks to CBSE.

What is the passing mark for CBSE Class 10?

You need 33% of the total marks (theory + internal) in each subject to pass. That means 33 out of 100. For theory alone, you need at least 33% of the theory marks. For a subject with 80 marks theory, you need at least 26 marks in theory AND 33 marks overall (theory + internal combined).

Can I get marks for wrong answers in CBSE Class 10?

There is no negative marking in CBSE Class 10 board exams. If your answer is wrong, you get zero for that part — but correct steps before the error still earn marks. This is why you should always attempt every question and show all working, even if you are unsure of the final answer.

How are CBSE Class 10 Science practicals marked?

Science practicals (20 marks internal assessment) include: lab experiments and activities, practical record/notebook, project work, and a viva voce. The school's Science teacher evaluates you. There is no external examiner for Class 10 practicals, unlike Class 12.

Does presentation matter in CBSE Class 10 board exams?

Presentation does not carry separate marks, but it directly affects whether examiners can find and award your marks. Neat handwriting, labelled diagrams, proper headings, underlined keywords, and bullet points make it easier for the examiner to identify correct steps. Messy answers risk missing step marks.
