How this guide differs from past-paper sites
The top Google results for KCSE Agriculture Paper 1 are mostly PDF downloads of old papers and marking schemes.

This guide adds that, with original questions and a timed online challenge with instant marking.
Frequently asked questions
What is in KCSE Agriculture Paper 1?
Soils, crops, pests and diseases and agricultural economics.
Where can I get the KCSE Agriculture Paper 1 marking scheme?
Official marking schemes are not published by KNEC for sale. Use practice papers with worked answers and the answers on this page, and be wary of anyone selling ‘marking schemes’ for the coming exam.
Are KCSE Agriculture Paper 1 leaked papers real?
No. Papers sold online before the exam are scams, and holding them is an exam irregularity that can lead to cancelled results (see KCSE exam rules).
How long is KCSE Agriculture Paper 1?
2 hours on the 2026 timetable.
Can I download the KCSE Agriculture Paper 1 2025 PDF here?
We do not host KNEC papers. Practise with original papers in the same format, with worked answers, in KCSE practice papers; schools keep past KNEC papers for their candidates.
Is there a KCSE Agriculture Paper 1 prediction for 2026?
Prediction papers are teachers’ practice papers, not the real exam. Use them like any past paper and focus on the topics listed above.
