Before you decide
What do I actually receive?
The PDF file itself, available as soon as you sign in. It is then listed in your TutorTech account, so you can download it again whenever you need it.
Is this a subscription?
No. Resources are bought once and kept. Nothing renews and there is nothing to cancel. Channels are the only recurring product on TutorTech — and a channel subscription includes the resources inside it, so check whether this one is already covered before you buy it separately.
Can I use it more than once?
Yes. Once it is yours you can print it, reuse it and revisit it as often as you like with your own students or your own children. Redistributing or reselling it is not allowed — it is the author’s work.
Can I see inside before I pay?
Yes. The preview section on this page shows sample pages from the resource itself, not a mock-up of it, so you can judge the standard before spending anything.
Who wrote it?
Mels, who publishes on TutorTech. Every author’s identity and qualifications are checked before anything they sell goes on sale, and their profile is linked at the top of this page. Resources are written and sold by the tutor — TutorTech provides the platform rather than authoring the content.
Where do I find it again later?
In your TutorTech account, under your resources. Everything you have bought stays there, and the download link never expires.
