Frequently Asked Questions

Live classes are booked as complete courses, apart from the warm-ups, which are single sessions.

1. See what is running on the live classes page.
2. On the booking page, sign up for a free account, or log in if you have one. Booking needs an account. This is separate from your login for self-paced courses, which will not work on the booking page.
3. Choose a course, click Book, fill in your details and pay by card.

You then receive a confirmation email, and reminder emails with the Zoom link 24 hours and 1 hour before each class.

If the booking page says it is unable to fetch class availability just after you log in, refresh the page.

Classes are grouped by age: 9-11, 11-13, 13-16 and 16-18. The live classes page links to each age group’s courses, and each course page says who it is aimed at.

Most maths challenge courses come in three levels:

• Core builds solid foundations across all the topics, for students aiming for Silver or Gold certificates.
• Advanced is for strong students aiming for Gold and hoping to qualify for the Kangaroo and Olympiad rounds.
• Elite is for students who are already well prepared and want the hardest problems, aiming to qualify for the Olympiad.

If you are not sure, Core is the usual place to start. The levels overlap, and many students take more than one.

Kevin’s free webinars for parents and teachers explain the courses and levels in more detail, and the live sessions end with an open Q&A.

If you would like a recommendation, send us a message with your child’s age and any recent exam or maths challenge results.

The Zoom link is in your confirmation email, and in the reminder emails sent 24 hours and 1 hour before each class. If you can’t find them, check your spam or junk folder.

You can also log in on the booking page to see your upcoming classes and their Zoom links.

Live class bookings are not refundable.

If the same course also runs at another time and has space, your booking can be moved to that time, as long as you ask at least 24 hours before the first class. Once a course has started, the booking cannot be changed. Send us a message to ask.

If a student misses a recorded class, the recording and notes are still emailed to everyone who booked.

Classes are recorded unless the booking description says otherwise. The recording and notes are emailed to everyone who booked, usually the same day, and stay available for at least 30 days.

If the live dates don’t suit, most courses can also be bought as recorded versions.

All class times are UK time (GMT in winter, BST in summer). The booking page can show times in your own time zone: choose it from the time zone menu above the list of classes.

Each class is for the age range shown. Younger students who are ready for it are welcome. Students older than the range, and adults, cannot attend.

We do not offer 1-1 tuition. Live classes are taught in groups on Zoom, and there are self-paced courses for every age from 7 to 18.

You can cancel at any time yourself, with no need to contact us. Cancelling stops future payments, and you keep access until the end of the period you have paid for.

• Most members: use the Stripe billing portal.
• If your payment receipts mention Lemon Squeezy: use the Lemon Squeezy billing portal.

Enter the email address your receipts go to, and you will be sent a link to sign in. From there you can cancel, update your card, or see past invoices.

A reminder email is sent 7 days before each payment. Payments already taken are not refunded, so cancel before the payment date.

The 11+ Maths Course is a one-off purchase, so there is nothing to cancel.

Use the same billing portal you would use to cancel: the Stripe billing portal for most members, or the Lemon Squeezy billing portal if your receipts mention Lemon Squeezy. Enter the email address your receipts go to, and you will be sent a link to sign in.

Self-paced courses are not refundable, because all the material is available as soon as you buy. Gold Membership payments are not refunded once taken; cancelling stops the next one. Live class bookings are not refundable either.

Yes. Many self-paced courses are completely free with a free account, and no payment details are needed. Parents and teachers can also watch Kevin’s free webinars, live or as recordings.

Courses, memberships and live classes are paid for online by card. We cannot take cheques, bank transfers, PayPal or childcare vouchers.

A purchase is attached to the email address typed in at the checkout, which is not always the address you are signed in with. Find the payment receipt for your purchase: the address it was sent to is the account your course is on.

Sign in with the receipt address

1. Open a private or incognito browser window, so you are not still signed in to another account.
2. Go to the sign-in page and sign in with the address your receipt was sent to.
3. If you have never set a password for that address, an account was created for it when you paid. Use Forgot your password to set one, and check your spam folder for the email.
4. Once you are signed in, open My Dashboard.

Go to your dashboard, not the course page

Open My Dashboard. A course’s own page is its sales page, so it asks you to pay even when you already own the course. Your courses are listed on the dashboard.

Live classes are not shown there. They are on the separate booking page.

Find the receipt

Search your inbox, including spam and junk, for emails about the purchase around the date you paid.

Check your bank or card statement too. If no payment was taken, the purchase did not complete, and you are welcome to buy again.

If it is still missing

Send us a message with the name of the course, the date you paid, and every email address you might have used.

Use the contact form: add your name and email address, and give as much detail as you can.

• For an account or technical problem, say what you were trying to do and what happened. You can also email screenshots to support@mathsaurus.com.

Mathsaurus does not run any competitions or exams and cannot enter students for them. Students usually enter through their school, so the first step is to speak to the school’s maths department.

• UKMT challenges, including the Junior, Intermediate and Senior Maths Challenges, are run by the UK Mathematics Trust.
• The Primary Maths Challenge and First Maths Challenge are run by AMiE, the Association for Mathematics in Education, at primarymathschallenge.org.uk.

Mathsaurus prepares students for these competitions, with free courses for many of them. Browse by age group from mathsaurus.com.
