Terms of use

Last updated: 8 November 2026

In short: use the site for your own study, or your own teaching. Don't share logins or copy the question bank.

1. Who we are

cbsemathrevision.com is operated by Pete Bromfield (UK sole trader). It is one of the Math Revision sites he runs (listed in the footer); they share one sign-in system and database. Contact: pbromfield@ibmathrevision.com.

2. Accounts

Students under 18 need a parent’s or guardian’s consent to use the site, or use it through their school under the school’s agreement with us. We don’t ask your age at sign-up. A parent can link their own account to follow progress (see the privacy policy). Accounts are personal: one account is for one person, and it can be used on up to 5 devices. You can remove a device on your account page (up to 3 removals in any 30 days; after that, email us and we’ll help).

3. What you can do

  • Use the site for personal study, or teach with it.
  • Print worksheets for your own classroom where a print option is offered.
  • Share links to the public pages freely.

4. What you can't do

  • Share your login.
  • Scrape or bulk-download the question banks, mark schemes or notes.
  • Republish our questions or solutions elsewhere without written permission.

5. Plans, trials and refunds

A free account opens chapter notes, formula sheets, board papers, our sample papers with their full step-marking schemes and the first step of every chapter, plus a small weekly allowance of AI marking. New accounts get 7 days of full access free, starting when they answer their first question, with no card. Changes apply to trials started after 8 November 2026: a free week that started earlier keeps the days it was given. CBSE Pro (prices in rupees here) opens every chapter question with its marking scheme, the Route to 95 checkpoints and the full common-mistakes library, with AI marking of written working (30 markings a month); CBSE Essentials, no longer sold since 13 October 2026, stays the same for anyone already on it, and both school plans (School and School Unlimited) include a monthly pool of AI markings shared by the school; when they are used up, you mark answers against the scheme yourself. Student plans renew each month or year until you cancel; individual plans bought at checkout start with 7 free days if you haven't had a free period with us before (one per person across our sites, the free week included; you are not charged until day 7), and cancelling before then costs nothing; otherwise the plan starts straight away, and checkout says so before you pay. Monthly card payments may need your approval with your bank for each renewal (RBI e-mandate rules). You can cancel at any time and keep access until the end of the period you paid for, and if you are not satisfied, email us within 14 days of your first payment for a plan, or of buying an exam pass, and we will refund you in full, even if you have used the site. Our refund policy is part of these terms and sets out renewals, school plans, how to ask and how to complain. Where offered, the CBSE exam pass (₹3,199) is a single payment for everything in CBSE Pro until 14 days after the last paper of the exams you choose at checkout (the board exams, or the Class 10 second board exam in May); the end date is shown before you pay and in your receipt, it does not renew (so there is no mandate to approve), it can't be bought while a CBSE plan of yours is set to renew, and the same 14-day money-back applies. School plans are yearly licences for a set number of student seats and teacher accounts; extra seats (in packs of 10) and extra teachers can be added for the rest of the licence year and renew with it. Teachers use the teacher tools free. Invite a friend rewards follow the terms on that page.

6. No guarantees of results

We help students prepare; we do not and cannot guarantee any exam result. Score ranges shown on the site are estimates.

7. Independence

This site is independent and not affiliated with, endorsed by or authorised by CBSE or NCERT. It is also not affiliated with, endorsed by or connected to the International Baccalaureate Organization. We never host past papers or mark schemes from the IB or any exam board: we link to the official copies only, and every question here is our own original work.

8. Changes and law

If we change these terms in a material way we will email account holders at least 14 days before. These terms are governed by the laws of England and Wales; this does not remove any consumer rights you have in India.
