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.
