Course Overview

This is the course syllabus for the IGCSE Physics 2023-2025 and 2026-2028 cohort with exam codes 0625 and 0972. The syllabi are exactly the same.

This course consists of a series of videos in English. I am working on adding notes and quizzes.

The course is almost complete, with the main topics already ready. I will be working on adding supplementary notes and video lessons, and I may also redo some of the video lessons to make them updated to the current syllabus. I will also be adding lessons on how to answer past year questions, as well as some worksheets for you to try.

A lesson I have not finished preparing is marked as “WIP” which means “Work in Progress”. If the lesson shows “Content Not Found” or if the lesson is not accessible, this means that the lesson is not ready and is still being developed.

General notes and video lessons are FREE.

Access to worksheets are currently restricted for selected students only.

  • Topical Worksheets
  • Topical Past Year Questions
  • Past Year Papers
  • List of definitions & equations
