How does ClearSteps AI evaluation work for CBSE?

Your child writes CBSE answers on paper, takes a photo, and uploads it to ClearSteps. The AI reads the handwriting, understands the answer, and marks it against the official CBSE marking scheme — the same criteria real board examiners use. It provides a mark breakdown with specific feedback on exactly what was missing.

Which CBSE classes does ClearSteps cover?

ClearSteps covers CBSE Class 8 through Class 12. For Class 8–9, it provides complete learning with concept videos, notes and quizzes. For Class 10–12, the CBSE mock papers and AI evaluation features are especially powerful for board exam preparation.

Which CBSE subjects are available on ClearSteps?

ClearSteps covers all major CBSE subjects for Class 8–12: Mathematics, Science (Class 8–10), Physics, Chemistry, Biology, English, and Social Studies. For Class 11–12, it also covers Accountancy. More subjects are added regularly.

Is ClearSteps a replacement for CBSE tuition teachers?

No. ClearSteps is a CBSE practice and evaluation tool — the practice partner a tuition teacher never has time to be. Students still benefit from a good teacher. ClearSteps makes that teaching stick through daily writing practice with real CBSE marking scheme feedback.

Can parents track their child's CBSE exam preparation on ClearSteps?

Yes. On Scholar and Family plans, parents get a dedicated login with a dashboard showing their child's subject scores, quiz results, CBSE mock paper history, weak topic areas, and daily study activity.

How much does ClearSteps cost for CBSE preparation?

ClearSteps has a free plan with 5 AI evaluations per day. The Scholar plan is ₹299/month with unlimited AI evaluations, all CBSE subjects, full mock paper library, and parent dashboard. The Family plan at ₹499/month supports 3 student accounts.

How to Use This Syllabus

Prioritise by marks

Use the unit-wise distribution above. Focus first on units with 20+ marks — they give the best return on study time.

Skip deleted topics

CBSE will not ask deleted topics in the board exam. Don't waste time on them — use that time for NCERT exercises instead.

Know the paper pattern

Section E (Case Study) has new-format questions many students ignore. Practise these separately — they're easy marks.

From syllabus to practice

You know the syllabus. Now practise it.

ClearSteps gives you chapter-wise mock tests aligned to the exact CBSE Class 12 Mathematics syllabus, with AI evaluation against the official marking scheme.
