Coverage and course references

All22 chemistry main headings are represented, with dedicated HL extensions for thermodynamics, kinetics, acid–base equilibria, electrochemistry, bonding, analysis and organic mechanisms. Statement-by-statement completeness is not certified.

Check the detailed course map and assessment references for the specification covered. Later exam sessions may use a revised syllabus. Notes and practice have not been independently verified throughout.
