You already solved the NCERT exercise in the notebook. The next step is not to retype the sum into a chat box. Photograph that page, confirm the text, and see marks the CBSE way. Snap & Grade on mentr.in is built for that loop: study the chapter PDF, practise the question, grade the handwriting. Class 9–12 Maths, Science, and Class 11–12 Physics, Chemistry and Biology — 3500+ questions on the same site.

Why a photo of your notebook beats typing

Boards are handwritten. If you only type answers, you never practise layout, units on the line, or the reason sentence. A photo keeps the exam muscle. Snap & Grade reads that page (you can edit the digital text if a line is misread) and scores it against the key already on the question.

  • Take the photo in good light, page flat, all working in the frame.
  • Confirm or edit the text before you grade — credits go only after confirm.
  • History stores question, marks, text, and tips — not the photo.

NCERT PDFs and questions in one place

On the Snap & Grade hub you can open Class 9–12 Maths, Class 9–10 Science, and Class 11–12 Physics, Chemistry and Biology chapter PDFs in the on-site reader. Study, practise, then grade. You do not need a second website for the PDF and a third for “check my answer”.

Start with one chapter tonight

  1. Open mentr.in/snapandgrade and pick your class page if you want subject copy first.
  2. Go to Grade now. Choose the exact NCERT question you wrote.
  3. Snap. Confirm. Read the step that was cut. Write that line again tomorrow.

Common questions

Can I grade any homework photo?
Today you pick a question from the bank we loaded (NCERT + board-style). Custom photo questions are coming later.
Do you store my photo?
No. History saves the question, marks, the text we graded, and tips — not the photo.
Which photo page should I open?
The hub is mentr.in/snapandgrade. Direct grader: mentr.in/snapandgrade/grade. Class landings such as /snapandgrade/class-10-maths explain the same tool for that paper.
