Every lesson, practice set, tool page and guide on this site is written by our team of teachers. We write to be useful first: a clear explanation, an original worked example and a way to check your own understanding.
This page explains how that work is done, so you can judge how far to rely on a page.
Who writes the pages?
We are a team of teachers who teach Cambridge IGCSE online, one to one. The pages reflect the explanations, examples and mistakes we meet in lessons. The content is independent of Cambridge.
How are lessons and practice sets written?
Each lesson states the skill, builds the idea step by step, then shows a worked example with every step visible. We add a mistake students commonly make and explain why it goes wrong.
All examples and questions are original, and every numerical answer shows its steps so you can check it.
Where do official facts come from?
Syllabus codes, exam years and entry rules come from Cambridge’s own pages, and where we cite them the page links to the source. You can start from the subjects we teach and then confirm details on the Cambridge subject page.
Cambridge updates syllabuses, and a code that applies to one exam year may not apply to the next. So we tell you what to check and where, instead of guessing. Paper numbers, durations, weightings, grade thresholds and dates should always be confirmed in the current syllabus.
How are sensitive topics handled?
History, Economics and Global Perspectives pages keep fact, source viewpoint and interpretation separate, and they stay neutral on politics.
For practical work and coursework, we teach the concepts and the permitted preparation. The work you submit stays your own.
How are pages kept current?
Each page shows an updated date. If you find something wrong, report it on WhatsApp and we review and fix it. See how to raise a factual correction.
Who is responsible for what?
We are an independent teaching service. Registration, entries, results and access arrangements are handled by your school or exam centre and by Cambridge.
Our pages help you understand and prepare, and what your centre or Cambridge confirms takes priority.
