Essential Biology is a core textbook for Nigerian senior secondary school students studying Biology for WAEC, NECO, and JAMB. Published by Tonad Publishers, it covers the complete biology curriculum from SS1 through SS3 and is widely adopted in classrooms across the country as a primary instructional resource.
The textbook covers cell biology, plant and animal nutrition, transport, excretion, nervous coordination, reproduction, genetics, evolution, and ecology in systematic detail. It is written at a level that supports genuine understanding rather than surface memorisation — an important distinction for WAEC Biology, where essay questions require students to explain processes accurately and in logical sequence.
For JAMB Biology candidates, Essential Biology provides the conceptual depth needed to handle the application-based questions that UTME sets alongside the recall-based ones. Students who study from it alongside their past questions are consistently better prepared than those who rely on revision notes alone.
