At Physics.Live we also keep all lectures for students who may have missed their online lectures for some reason or just want to have a recap, this helps students to keep up with the lectures and also makes sure that every topic and concept is thoroughly understood.
With years of experience of teaching, we also have a set of highlighted concepts that we believe are a little harder for students to grasp as compared to the other. For such concepts and topics, we have a set of additional video lectures for easy understanding.
During and after the lectures you must practice and take tests to make sure that you have understood clearly. We have 1000+ hours of video lectures and we keep adding the latest almost every day!
