Terms of service
Last updated 13 September 2026
These terms apply whenever you book a free trial, a lesson, a 5-pack or coursework feedback with Cognivia Tutoring. By booking, you agree to them.
About us
Cognivia Tutoring is run by Archie Dyer and based in Marylebone, London. You can reach us at cogniviatutoring@gmail.com or on +44 7535 185867. In these terms, “we” and “us” mean Cognivia Tutoring, and “you” means the parent, guardian or student making the booking.
Our services
1-hour, 1:1 lessons in Maths, Physics, Chemistry and Economics, for IGCSE, GCSE, A-Level, IB (SL and HL) and the TMUA and ESAT admissions tests. We don’t run group classes.
Lessons take place online via Google Meet, or in person around Marylebone, London. In-person lessons cost £10 more than online lessons.
5-packs: five 1-hour lessons, paid for in advance, with £15 off.
A free 30-minute trial lesson, online via Google Meet. No card is needed.
Coursework feedback: detailed written comments on your work within 5 days. Work up to 1,500 or 3,000 words also includes a 30-minute call to go through the feedback.
After each lesson, parents receive a short note on what was covered and what to practise next.
Booking and payment
You book through our website. Parents can book for their child, and students can book for themselves. Lesson times are shown in your own time zone.
Prices are in pounds sterling (GBP) and are as shown at the time you book.
Payment is taken upfront when you book, securely through Stripe. You can pay by card, Apple Pay or Google Pay.
Your card details are handled by Stripe. We never see or store them.
After buying a 5-pack, your 5 lessons are added to a My lessons account linked to the email you paid with. You log in with that email and a code we email you, then book the lessons one at a time, whenever suits you. Each booking uses one lesson.
Cancelling and rescheduling
To cancel or reschedule, contact us by email or phone at least 24 hours before the lesson. You’ll get a refund or a credit. Lessons can’t be cancelled online, so please get in touch directly.
Cancellations with less than 24 hours’ notice, and missed lessons, are charged in full. For a 5-pack, that lesson counts as used.
If we have to cancel, you can choose to reschedule or get a full refund.
Lessons from a 5-pack can’t be moved or cancelled in My lessons. To move or cancel one, contact us by email or phone at least 24 hours before. If we cancel a lesson from a 5-pack, it’s returned to your My lessons account so you can book another time.
If a student joins late, the lesson still ends at its scheduled time.
Coursework feedback
Feedback is priced by word count: £50 for up to 750 words, £100 for up to 1,500 words and £200 for up to 3,000 words.
Email your work to cogniviatutoring@gmail.com. We return detailed written feedback within 5 days of receiving it. For work up to 1,500 or 3,000 words, a 30-minute call to go through it is included in the price; you book the call at least 5 days ahead.
Feedback is guidance only. We never write any part of the work. Students remain responsible for their own work and for following their school’s and exam board’s rules.
Online lessons and safeguarding
Archie Dyer holds an Enhanced DBS check.
Online lessons take place on Google Meet. The meeting link is in your booking confirmation email.
Students under 18 need permission from a parent or guardian to take lessons.
For students under 18, a parent or guardian should be at home during online lessons.
Lessons are not recorded.
We expect respectful behaviour from everyone. We may end a lesson early if behaviour is inappropriate.
Results
We’ll always do our best to help students progress, but we can’t guarantee specific grades or results.
Liability
Nothing in these terms limits any liability that can’t be limited by law. If a lesson can’t go ahead because of a technical problem on our side, we’ll reschedule it.
Changes to these terms
We may update these terms from time to time. The version shown on this page when you book is the one that applies to that booking.
Law
These terms are governed by the laws of England and Wales.

Accessibility
Last updated 13 September 2026
We want everyone to be able to use this website. We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA.
What we’ve done
You can move around the site with a keyboard, and a visible outline shows where you are.
Text is large and easy to read, and text and controls use good colour contrast.
Images have text alternatives.
Animations switch off when “reduce motion” is turned on in your device settings.
Third-party pages
The booking calendar is provided by Cal.com and the payment pages by Stripe, so their accessibility is managed by those providers.
