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 PYQs Effectively

Attempt under exam conditions

Set a 3-hour timer. No phone, no notes. Treat every PYQ as a dress rehearsal for the board exam.

Identify repeating patterns

Chapters that appear in 2 or more years are guaranteed important. Prioritise those in your revision.

Track your score year by year

Do 2023-24, then 2024-25, then 2025-26. If your score improves, you're on the right track.

Plug gaps with chapter practice

Every wrong answer points to a weak chapter. Practice that chapter on ClearSteps before moving to the next paper.

From papers to marks

Know your weak spots. Fix them before the exam.

ClearSteps gives you chapter-wise mock tests for CBSE Class 12 Chemistry with AI evaluation against the official marking scheme — so you know exactly where you stand.
