Question Bank
How to use the Question Bank
Four steps, that is the whole method.
- 1
Pick a chapter
Choose a subject, then a chapter. Every question inside is an official CBSE one.
- 2
Attempt on paper
Work it out properly before you look. The struggle is what makes the method stick.
- 3
Reveal official answer
Tap to compare. The reveal stays locked until you have had a go.
- 4
Explain or Check my answer
Stuck, or unsure how many marks you would score? Ask Buffy.
- MCQ Tap your option, then Check — Buffy tells you why it is right or wrong.
- Written Type your key steps, roughly. The marks come from the method.
The official answer wins
The official CBSE answer is the authority. AI help is a study aid, and any AI-worked solution is worth a check with your teacher.
Daily AI limits
Explain and Check my answer are free but capped per day. If you hit the cap, every question and official answer stays open.
Every question is official
Nothing here is AI-generated practice. Each question and answer is verbatim from an official CBSE publication, with the source and page shown on the chapter page.
For parents
- 5–8 questions per chapter per week beats one long cram session.
- Ask them to explain the method out loud, not just show the final answer.
- Check my answer grades the steps they wrote, not just the final answer — step marks are where the half-marks are won or lost.
