Browse Biology KCSE past-paper files by year, paper number and available alternative. This archive brings together 126 distinct resource links from existing KCSERevision collections.
Archive labels: Paper and marking-scheme columns follow the original source labels. Confirm the paper code and question numbering before using an answer file. Combined papers and year ranges stay combined; unclear dates, paper numbers and missing separately labelled answers are shown explicitly.

Use the correct paper and marking scheme
Choose the examination year and paper number first. Check the alternative, paper code, practical instructions and question numbering before using an answer file. A combined marking scheme may cover several papers; its filename remains visible so you can confirm which part applies. Dates inferred from a single-year source collection should be checked inside the document.
