About Questo
Eliminating guesswork from CBSE board examination preparation through examiner-grade handwritten step evaluation, textbook page citations, and transparent parent diagnostics.
Why We Built Questo
Every year, hundreds of thousands of CBSE Class 10 and 12 students write full answers, memorize formulas, and study for months, only to be surprised when their board marks fall 10–15% lower than expected. The issue is rarely a lack of knowledge—it is the difference between knowing a concept and presenting it according to the official CBSE step marking scheme.
Questo bridges this gap. Using multimodal vision AI grounded strictly in NCERT textbooks, Questo checks students’ actual physical handwritten answer sheets, validates algebraic derivation steps, checks ray diagram labels, and provides constructive examiner feedback within 60 seconds.
NCERT Grounding
Zero hallucinations. Every critique, formula derivation check, and correction cites the exact chapter and page in official NCERT books.
Step-Wise Marking
Marks are awarded for intermediate mathematical steps, unit labeling, and diagram presentation, mirroring the CBSE chief examiner rubric.
Zero-PII Privacy
Student answer sheets and identities remain confidential. Uploaded sheets are processed in secure enclaves and never used for public training.
