Terms of use

The short version: the worksheets are free to use, print and hand out, including in a classroom, and you need no account to do any of it. They come with no warranty, and the answer keys can be wrong — check them before you rely on them. Accounts exist too: a tutor can make one, and a student or parent can with their tutor's join code.

Who we are

Discia is operated by Mashdup Limited, a company registered in England & Wales (company number 17020411), registered office 124–128 City Road, London, England, EC1V 2NX (“we”, “our”, “us”). Contact us at privacy@discia.org.

By using this site you accept these terms. If you do not accept them, please do not use the site.

What Discia is

Discia publishes free printable GCSE mathematics worksheets with answers. Everything on the public worksheet site — the worksheet pages, the answers, printing from your browser and the downloadable PDF — is available to anyone, free and without an account. There is no advertising anywhere on it, and no third party learns anything about your visit.

We take no payment. There is no price, no checkout, no card form and no payment provider connected to this site, so nothing here can charge you for anything. We can put an account on a plan — an administrative record we create by hand, which is how we expect to handle a tutoring family or a school — but there is no way to buy one. Today a plan does one thing: a tutor on one has no limit on how many students they teach here (see Tutors).

There are also accounts — for practice that is saved, marked and tracked over time. Tutors can create an account. A student or a parent can create one only with a tutor's join code, or with an invitation from us; without one of those there is no sign-up for them.

What you may do with the worksheets

Once you have a worksheet from us, you may use, print, copy and pass it on for study and for teaching, including printing class sets and sharing them with students, colleagues and parents. You do not need to ask us first. This permission is about the sheet itself: it does not expire, and it does not depend on holding an account or on how you came by the sheet.

Getting hold of one is a separate question, and today the answer is that every worksheet page, the answers, printing from your browser and the downloadable PDF are free to everyone and need no account. We have written into the site — and not switched on — a limit on how many worksheet PDF files a signed-in account may download in a calendar month. If we ever switch it on, this page and the privacy policy will say so first. The worksheet pages themselves, the answers and printing from your browser are not part of that limit.

You may not:

• sell the worksheets, or charge for access to them;
• republish them in bulk on another website or in a product, whether free or paid, or present them as your own work;
• scrape the site automatically at a rate that degrades it for other people.

Attribution is welcome but not required. If you want to do something these terms do not allow, ask us — the answer is often yes.

Accounts

If you have an account, these additional terms apply to it.

• An invitation is personal and works once. It is issued to one named person, creates one account, and stops working the moment it is used. Please do not pass yours on. If you lose it, ask us and we will issue a new one — we cannot recover the old one, by design. A tutor's join code is different: it is meant to be given to the families the tutor teaches.
• Choose the right kind of account. Whether an account is a student, a parent or a teacher account is decided by the invitation, or by what you choose on the tutor sign-up form or a tutor's join page (student or parent).
• Keep your password to yourself, and tell us at privacy@discia.org if you think someone else has it. You are responsible for what is done with your account.
• Resetting a password needs a confirmed email address. If there is an address on your account, we will send you a link to confirm it; once it is confirmed you can reset your own password from it. Accounts with no address, or with an address that has never been confirmed — including most children's accounts, because we do not ask a child for an address — cannot be reset that way, and we change the password by hand instead. An address can only be confirmed on one account.
• Give accurate details — in particular a real date of birth, which is what decides whether an account needs a parent to set it up.
• One account per person. Do not create an account for someone else except as described below for your own child.
• We may suspend or close an account that breaks these terms, or that is being used in a way that puts another user at risk. Where it is reasonable to do so we will tell you first.
• You may close your account at any time by emailing privacy@discia.org, or, for a student aged 13 or over, on the Your choices page in the app. It closes at once, and we delete it and the practice data attached to it 30 days later.

Children and parents

Discia is a GCSE mathematics site, so we expect under-18s to use it.

• Under 13, a child cannot set up their own account. It is created by their parent or guardian, who must be 18 or over: from the parent's own account, confirming by email, or with an invitation from us. Doing so records their consent, and we log the dates and the version of our privacy policy in force at the time.
• From 13, a student consents for themselves: in person in lessons with their tutor, and in the app the first time they sign in. A child is asked again for themselves after turning 13.
• A parent account can see its linked children's work — their grades, their practice sessions, the answers they gave, and the progress reports their tutors send. For a student aged 13 or over, only if the student has said yes. If you set up an account for your child, you are confirming that you hold parental responsibility for them.
• Consent can be withdrawn at any time: by the parent, on their home page or by emailing us, for a child under 13; by the student, in the app, from 13. We close the account at once and delete it and its practice data 30 days later.

None of this applies to the worksheet pages, which remain open to everyone with no account and no sign-in.

Tutors

A tutor account gives no access to any student until a family adds the tutor with their join code and the tutor accepts, or we link them. Discia does not check tutors: a tutor must give their real name and confirm in our tutor terms that they are not barred from working with children. The free plan is for up to 2 students at a time, and a student who leaves still counts for 30 days. A plan we grant by hand removes the limit; if it ends with more students than that, the tutor has 14 days to remove some before their tutor tools lock until they do. Their students lose nothing either way.

Where the questions come from

The questions and answers published here are generated by this site. They are written to match the GCSE mathematics curriculum, but they are not past-paper questions and are not endorsed by, affiliated with or approved by any exam board. Where a topic name matches exam-board terminology, that is description, not endorsement.

No warranty

The worksheets are provided “as is”. We take care with them, but questions and answer keys are generated automatically and may contain errors. Nothing here is a substitute for teaching, a textbook, or your exam board's own specification and materials.

The same goes for anything an account shows you. Marks, grades and the confidence estimates drawn from a student's answers are produced automatically from practice on this site. They are a study aid, not an assessment, and they predict nothing about an exam result.

We give no guarantee that using this site will improve any grade or exam result, and we do not warrant that the site will be available, uninterrupted or error-free. We may change, suspend or withdraw any part of it at any time.

If you spot a mistake in a question or an answer, please tell us at privacy@discia.org — it helps everyone using the site.

Our liability

Nothing in these terms limits our liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be limited.

Subject to that, we are not liable for any loss arising from your use of, or inability to use, this site, or from reliance on any content on it — including loss of profit, loss of opportunity, or examination outcomes. The site is provided free of charge.

If you are using the site as a consumer, these terms do not affect your statutory rights.

Acceptable use

Please do not attempt to gain unauthorised access to the site or its servers, interfere with its operation, or use it to break the law. We may restrict access if you do.

If you hold an account, that also means not attempting to reach another user's account or another student's work, and not guessing or collecting invitation codes or other tutors' join codes, and not passing on an invitation meant for you.

Privacy

Reading a worksheet tells us essentially nothing about you. An account tells us more, and if it belongs to a child we record a parent's consent for it. Our privacy policy explains what our server logs record, what an account stores, who can see a student's work, and how long any of it is kept.

Changes to these terms

We may update these terms. The version and date below will change when we do, and continuing to use the site means you accept the current version.

Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction, save that if you are a consumer resident elsewhere in the UK you may bring proceedings in your own jurisdiction.
