CambridgePreparationAI is an independent English exam-preparation platform offering AI-generated Reading & Use of English and Writing practice for B2, C1, and C2 learners.
All exercises and their related passages, prompts, questions, answer options, answer keys, model answers, explanations, scoring guidance, and feedback made available through CambridgePreparationAI are created using artificial intelligence. Content may be reviewed or edited, but it remains AI-generated and may contain errors, omissions, inconsistencies, or material that is unsuitable for a particular learner or purpose.
The exercises are independently generated and are not official Cambridge English materials. They are not official past papers, sample papers, question banks, answer keys, marking schemes, or publications supplied, reviewed, approved, endorsed, or authorised by Cambridge University Press & Assessment, Cambridge English, the University of Cambridge, or any of their affiliates.
CambridgePreparationAI is an independent exam-preparation platform. It is not part of, affiliated with, endorsed by, or approved by Cambridge University Press & Assessment, Cambridge English, the University of Cambridge, or any of their affiliates. It is not an official Cambridge English product, exam centre, or preparation centre.
Cambridge, Cambridge English, and related names and marks belong to their respective owners. References to third-party exams or qualifications are descriptive only and do not imply sponsorship, endorsement, or official status.
Use of CambridgePreparationAI does not guarantee any score, grade, pass, certification, admission, improvement, or other result on any exam. Performance on the platform may not predict performance in an actual exam, and official exam content, format, difficulty, rules, and marking may differ. Users should consult the relevant official exam provider for current specifications, regulations, and official preparation materials.
2. How CambridgePreparationAI access-pass billing works
CambridgePreparationAI sells one-time fixed access passes for digital English practice access to AI-generated exercises and related features. Access passes are digital products/services, and no physical goods are shipped.
Access starts after successful payment confirmation and is delivered electronically inside the user's CambridgePreparationAI account.
Each order unlocks the levels and access period shown at checkout. A pass may unlock B2, C1, C2, or a bundle of levels.
Access passes do not auto-renew. If you want access after a fixed-term pass expires, you must make a new purchase.
Payments, taxes, invoices, checkout operations, fraud checks, disputes, chargebacks, and refunds may be handled by Dodo Payments as payment provider and Merchant of Record. Dodo Payments' buyer terms and refund processes may also apply.
CambridgePreparationAI may provide free samples, previews, or example AI-generated exercises so users can review parts of the product before paying.
3. One-time purchases and access expiry
Because access passes are one-time purchases, there is no recurring billing to cancel.
A fixed-term access pass normally ends automatically at the end of the stated access period. A lifetime access pass remains subject to the Terms of Service and any lawful service limitations.
Buying another level later adds that level separately if it is not already active. You cannot repurchase a level while that level is already active.
4. Withdrawal rights and digital access
Depending on where you live, you may have a legal right to withdraw from an online purchase within a specific period, such as 14 days.
Because CambridgePreparationAI is a digital service that may provide immediate access to AI-generated digital content, exercises, practice flows, and AI-powered tools, your withdrawal or refund rights may be limited once access has started, where allowed by law.
Where required by law, CambridgePreparationAI or Dodo Payments may ask you to expressly agree that digital access begins immediately and acknowledge that you may lose your right of withdrawal once access or performance begins.
Nothing in this Refund Policy removes or limits any mandatory consumer rights that apply to you.
5. Refunds for digital access
Because access is delivered instantly after payment, refunds are reviewed case by case and are not guaranteed. If a refund is approved, it will be processed to the original payment method via Dodo Payments. Refunds, disputes, or chargebacks may result in revocation of the related access pass.
For refund reviews, users should contact support@cambridgepreparation.ai within 14 days of the charge they want reviewed. Requests made later may still be considered where required by law or where exceptional circumstances apply.
Refunds may be considered where:
- there was a duplicate charge or another clear billing error;
- paid access was not delivered because of a confirmed technical issue and support could not resolve it within a reasonable time;
- the wrong access pass or charge was applied because of a checkout or account error;
- a refund is required by applicable consumer law;
- CambridgePreparationAI decides that a refund is appropriate in fairness.
Refunds are generally less likely where paid access was successfully delivered and meaningfully used, unless applicable law requires otherwise.
A difference between the AI-generated exercises and an official exam's content, format, difficulty, or marking, or an exam result that does not meet your expectations, does not by itself mean that digital access was not delivered and does not automatically create a right to a refund. This does not limit any mandatory consumer rights that apply to you.
6. Billing errors, duplicate charges, and access problems
If you believe you were charged in error, charged twice, or did not receive the access pass you purchased, contact support as soon as possible.
Please include:
- the email address linked to your CambridgePreparationAI account;
- the access pass purchased;
- the date of the charge;
- any receipt, invoice, checkout reference, or transaction reference you have;
- a short explanation of the issue.
If you paid but could not access the purchased service, contact support within 7 days of the issue appearing when possible.
We may ask you to complete reasonable troubleshooting steps before deciding whether to issue a refund, account credit, access extension, or another remedy.
Where a technical problem is confirmed and paid access was not effectively delivered, CambridgePreparationAI may choose the remedy that best fits the issue, including restoring access, extending access time, issuing an account credit, or granting a refund where appropriate.
7. Refund method and timing
If a refund is approved, it will be processed to the original payment method via Dodo Payments unless Dodo Payments requires or allows another method.
Refund timing depends on Dodo Payments, the card network, bank, wallet provider, or checkout system involved.
CambridgePreparationAI cannot control every delay caused by third-party payment systems, banks, card networks, or payment providers.
8. Chargebacks and payment disputes
If you have a billing issue, please contact support@cambridgepreparation.ai first so we can review it.
If you open a chargeback or payment dispute, your access may be suspended or revoked while the dispute is being reviewed by Dodo Payments, the bank, or the card network.
A refund, chargeback, or payment reversal may result in revocation of the related access pass.
9. How to request a refund review
Send refund-related requests to:
support@cambridgepreparation.ai
Include the email address linked to your account, the access pass purchased, the date of charge, and a short explanation of the issue.
Submitting a request does not guarantee that a refund will be granted. Each request is reviewed in light of this policy, the account circumstances, product access history, any troubleshooting already attempted, Dodo Payments' rules, and applicable consumer law.
