Chemistry - handwritten notes (Coordinated Sciences 0654)


Here are handwritten Chemistry notes for the IGCSE CIE 2022 syllabus (Coordinated Sciences). They can be downloaded in full or by chapter. 

You can download each chapter by following the link on the right upper corner of each pdf file. I've been creating these notes to tutor students preparing for the exam, and will upload more chapters as I continue completing them.

Be sure to let me know if there is anything you need to aid your studies!



Most of the diagrams/graphics can be credited to Save My Exams. I do not own these graphics.

Some colored markings:

  • red: questions you can answer to test your 
  • orange: examples you can try out yourself!
