Who Wrote These Notes?
Every eBook in this library is written by Hosni — a published science author with nine years of experience writing and refining these resources, and decades spent examining IGCSE and IAL papers for Cambridge and Edexcel. That examination experience is the reason these notes are written the way they are: structured around what examiners award marks for, using the exact language mark schemes reward, and stripped of everything that costs students time without earning points. With over 20,000 copies sold every year across more than 40 countries, and a commitment to updating every eBook after each exam sitting using the latest mark schemes and examiner reports, these are not static revision notes — they are a living resource that stays current so students always revise against the correct specification.
Everything the Examiner Wants. Nothing They Don't.
Four features that make these eBooks genuinely different from anything else students will find.
Built From the Mark Scheme Down
Notes are written starting from what examiners award, not from the textbook. Every point, every keyword, every answer structure reflects the mark scheme.
Copy-Ready Answer Language
Students learn the exact phrasing examiners reward. The notes teach how to construct answers, not just what to revise.
QR Video Explanations & Quizzes
Every topic links to an explanatory video via QR code. Built-in interactive quizzes and flashcards let students self-test immediately.
Updated After Every Exam Sitting
These eBooks are revised using the latest mark schemes and examiner reports after every sitting, so students always revise against the current standard.
