New School Chemistry for Senior Secondary Schools by Osei Yaw Ababio is the textbook most Nigerian chemistry teachers still recommend first — and for good reason. It has shaped how chemistry has been taught in Nigerian secondary schools for decades.
The book takes you from the basics of atomic structure and the periodic table through to organic chemistry, electrochemistry, and quantitative analysis, with diagrams that make abstract reactions easier to visualise and practice questions at the end of every chapter.
If you’re preparing for WAEC, NECO, or JAMB Chemistry, New School Chemistry remains one of the most syllabus-aligned resources available — it’s the book most past-question answers are explained against.
