2024 JAMB Biology Past Questions
Browse the 2024 JAMB Biology past questions with answers and step-by-step explanations. Biology demands precise terminology and careful diagram reading. Successful candidates revise plant and animal physiology, ecology and genetics with active recall — and rehearse the standard practical setups before exam day. Use the year archive below to time yourself the way the actual exam does — most candidates need to work questions across multiple years before the patterns become obvious.
