Over the years, KCSE chemistry questions follow clear patterns, making past papers an essential tool for understanding what examiners expect.
All past papers are neatly arranged by year to allow quick and easy access. Each year includes:
- Paper 1
- Paper 2
- Marking Schemes (where available)
To make revision easier, we have organized past papers by year, from oldest to recent papers available, all accessible in one place.
