PAPER THREE · LEGAL
Terms of service
Effective 30 September 2026
These terms apply to paper3physics.com, an independent educational website operated by ZHAO JIFENG, an individual in mainland China. For course, purchase, or legal questions, email jintlgs@163.com.
What the website offers
Paper Three teaches practical skills for Cambridge International AS & A Level Physics 9702 Paper 3. Lessons 1.3, 2.2 and 3.4 and the examination overview are free. The full course is a one-time digital purchase giving the buyer personal access to the current set of 11 other lessons written by Jeff, together with corrections to those lessons while the service operates. It is self-paced. It does not include live tutoring, future courses, or Cambridge past-paper questions or mark schemes.
Paper Three is independent and is not affiliated with or endorsed by Cambridge International Education. It does not guarantee an examination result.
Price and checkout
The advertised full-course price is US$19, paid once. There is no subscription or automatic renewal. The final amount and any applicable tax are shown before you confirm payment. Waffo Pancake is the merchant of record for the sale and handles checkout, payment, tax, receipts and payment-related refunds under its Buyer Terms. These website terms govern delivery and use of the course.
Access and delivery
After Waffo confirms a successful payment, the website grants access to the 11 paid lessons. A browser session keeps you signed in for up to 180 days; you can restore access on another device with the recovery key shown after purchase. Keep that key private. If the key is lost or delivery fails, email jintlgs@163.com with your Waffo order receipt so we can help. Do not send payment-card details by email. Clearing your browser may erase locally saved lesson progress, which does not currently sync between devices.
Refunds and purchase problems
If you cannot access paid lessons or the course is materially different from its description, contact jintlgs@163.com so we can investigate and help resolve it. You may request a refund through the Waffo Buyer Portal linked from your receipt, subject to Waffo’s Buyer Terms and refund process. Waffo reviews and processes refund requests. A completed refund ends access to the paid lessons. Nothing here limits rights that cannot be excluded under applicable consumer law.
Permitted use
Access is for the buyer’s personal study. The lessons, illustrations and site design remain the property of their respective rights holders. You may not share a recovery key, resell access, republish lesson material, or attempt to bypass the access controls. You may quote brief excerpts with attribution where the law permits. We may suspend access used fraudulently or in material breach of these terms, and will respond to a support request about any suspension.
Students and purchases
The learning material is intended for students aged 16 or older. Anyone under the age of majority where they live should have a parent or guardian make and manage a purchase. Payment eligibility is also governed by Waffo’s checkout terms.
Changes and availability
We may correct lesson content and maintain the website. We will post material changes to these terms here with a new effective date. If the course service is to close, we will give reasonable notice on the website and explain the access and refund options available at that time. Internet services can be interrupted; contact support if access is unavailable.
Privacy and contact
Our Privacy Policy explains how this website handles information. For any question about these terms or the course, email jintlgs@163.com.
