CBSE Class 12 Chemistry Sample Paper 2026–27: Official PDF and Review Plan
CBSE Academic has published the Class XII Chemistry (043) sample question paper and marking scheme for 2026–27. Download both from the official subject table so the session, subject code and answer guidance match.
The paper is a model of the current design, not a prediction of the exact 2027 board questions. Its value comes from a timed attempt, honest marking and a repair plan for the concepts and answer-writing steps that cost marks.
Download the official pair
Open CBSE's Class XII 2026–27 sample-paper table and choose Chemistry SQP and MS. Keep the marking scheme closed until the timed attempt ends. The official curriculum remains the authority for the complete examinable scope.
Use the correct exam conditions
The curriculum specifies a three-hour, 70-mark theory paper, with a separate 30-mark practical component. Read the SQP instructions for its exact section structure and internal choices before starting.
- Set aside an uninterrupted three-hour window and use only permitted materials.
- Show equations, units, structures, conditions and reasoning that earn marks.
- Mark questions that felt uncertain or slow even when the final answer was correct.
- Do not pause the clock to revise a chapter or check an answer.

| Error | What to inspect | Repair task |
|---|---|---|
| Concept | The principle, trend or reaction pattern was unclear | Relearn it and solve two contrasting questions. |
| Recall | A reagent, condition, observation or definition was missing | Use spaced retrieval, then apply it in context. |
| Calculation | Formula choice, substitution, unit or arithmetic failed | Rewrite the full method and complete a short accuracy set. |
| Answer writing | A step, equation, structure, condition or explanation was absent | Rewrite against the official marking points. |
| Time | Known work remained unfinished | Practise timed sections and question selection. |
Review by branch of Chemistry
- Physical Chemistry: check setup, units, assumptions and interpretation, not only the final number.
- Inorganic Chemistry: connect the recalled fact to a trend, observation or explanation.
- Organic Chemistry: verify the starting material, reagent, condition, product and reasoning for the route.
- Biomolecules: use precise structures, classifications and terminology required by the question.
A seven-day correction cycle
- Day 1: attempt and mark the paper; list every lost or uncertain mark.
- Days 2–3: repair the two largest concept clusters using the textbook and focused questions.
- Day 4: rewrite weak answers with complete equations, structures and reasoning.
- Day 5: retry missed questions without the scheme.
- Day 6: complete a new timed mixed section.
- Day 7: review whether the same error types reduced before scheduling another full paper.
What parents should look for
One mock score is not a forecast. Look for whether the student can explain the correction, whether repeated errors decrease and whether the next week's plan names exact chapters and tasks.
- Keep the attempted paper, marked scheme and error log together.
- Separate knowledge gaps from time and presentation problems.
- Schedule correction before another mock.
- Seek focused teaching when the same concept survives two serious correction attempts.
Frequently asked questions
Is this the official 2026–27 Chemistry sample paper?
The links lead to CBSE Academic's official Class XII 2026–27 table. Select Chemistry (043) SQP and its matching marking scheme there.
Does the sample paper predict the 2027 board paper?
No. It demonstrates the current design and expected response style. Students must prepare the complete prescribed curriculum.
When should I attempt it?
Attempt a full timed paper after broad syllabus coverage. Earlier in the year, use selected questions as diagnostics without treating the score as a full-paper result.
