About

Welcome to Dereck Tafuma — an independent education blog focused on practical GCSE and A-Level revision.

Who I am

I'm Dereck Tafuma, an educator and the founder of RevisionLab. My work includes building revision resources and private study hubs that help students turn broad subjects into manageable tasks.

I started this blog after repeatedly seeing capable students work hard with methods that gave them very little useful feedback. The aim here is simple: explain what to do, why it helps, and how to apply it to a real revision session.

What you will find here

• subject-by-subject revision guides for GCSE and A-Level;
• practical exam technique and mark-scheme advice;
• study-planning, concentration and wellbeing guidance;
• clear explanations of revision methods such as retrieval practice and interleaving; and
• occasional behind-the-scenes articles about building RevisionLab.

How the content is prepared

Every published article should answer a specific student or parent question and contain steps that can be used in practice. Where a post depends on changing information — such as exam dates, application procedures or an exam-board requirement — I check the relevant official source and update or withdraw the article when it is no longer reliable.

Subject guides on this site are general UK revision guidance, not a replacement for your own exam-board specification, school advice or teacher feedback. Students should always use the specification and materials for the exact qualification they are taking.

Editorial independence and corrections

This blog is independent. It is not affiliated with or endorsed by an exam board, UCAS, a school or any app mentioned in an article unless a page clearly says otherwise. Paid placements and affiliate links, if introduced, will be identified clearly.

If you spot an error, an outdated link or wording that needs clarification, please use the Contact page. Useful corrections are welcome and will be reviewed.

Thanks for reading. The goal is not to help students revise for longer; it is to help them practise more deliberately and learn from the result.
