The teacher behind the results.
Hosni Showike is the author of eight published science textbooks with more than 20,000 copies sold worldwide. He has taught IGCSE and International A Level Chemistry and Biology for over 20 years, including 16 years teaching to Cambridge and Edexcel mark schemes at A-level, and writes at chem-bio.info where he publishes grade-threshold analysis, solved past papers and live exam-preparation classes.
My promise is simple: every lesson is written in the language of the mark scheme, so what you learn is exactly what earns marks. That's how my students' answers end up featured in examiner's reports — and how one attained the highest mark in Kuwait for Edexcel IAS Biology in January 2024.
