WAEC Physics Practical Questions

The West African Examinations Council (WAEC) is an examination board that conducts the West African Senior School Certificate Examination, for University and Jamb entry examination in West Africa countries. In a year, over three million candidates registered for the exams coordinated by WAEC.

The Waec Physics practical Alternative A will take place on an announced Date and the Physics Practical Alternative B will be written on a subsequent date.

The physics practical is usually divided into 3 questions (comprising of Mechanics, Waves and Electricity) with a few other general knowledge calculations.
