evidencechidozie@gmail.comIn Nigerian secondary schools, physics is taught as a foundational topic, mostly to students in the science stream. In-depth discussions of mechanics, electricity, thermodynamics, and optics are included as it explores matter, energy, and their interconnections. For students who want to take university courses in computer science, engineering, physics, or astronomy, this topic is essential. Because it offers the fundamental concepts needed for various professions, it also plays a big part in national exams like WAEC, NECO, and JAMB. Jamb Physics Past Questions.
