Welcome to your Physics class. Video lectures on SHS 1 Physics are now available. Preview is FREE. Kindly note that more videos, notes and quizzes will be added to cover the syllabus. You can play, replay and pause the lecture to take down notes. The forum is for further discussions on the lessons. Wolo is indeed a smart way to learn
