FAQ
Straight answers
What is Snap & Grade?
Snap & Grade is Mentr’s CBSE practice tool. You pick a Class 9–12 NCERT question, photograph the answer you already wrote, and get step marks the way a board examiner awards them — plus short tips on how to write it next time.
Who is it for?
Students in Class 9–12 who have practised the chapter but still don’t know what they would score. Parents who want a clear mark sheet, not a vague “looks correct”.
Which classes, subjects and papers are covered?
CBSE Class 9–12. NCERT Maths, Science, and Class 11–12 Physics, Chemistry and Biology question banks are live. Board papers, PYQs and sample papers for Class 10–12 sit in the same practice flow — pick a question, snap your work, get full step marking.
How is this different from ChatGPT or other AI?
ChatGPT guesses from whatever marking scheme you upload. Snap & Grade already has a CBSE-style key on every question — formula, working, units, final answer. You don’t hunt a PDF. You pick the question and see marks the way CBSE splits them.
Why do students lose marks even after practising?
About 3 in 10 students lose marks because they don’t know how to write the answer — missing a step, units, or the statement the examiner wants. Snap & Grade shows which step was cut and how to write it in the exam.
How do credits work?
New accounts get 100 free credits once. A full step-marked check uses about 5 credits. After that, recharge from ₹1 (₹1 = 1 credit) via Razorpay. Credits stay on your account.
