Very lengthy question set. But its useful to understand the concepts and had a practice of doing many problems with slight twists. Got a clear idea for solving the DC circuits.
Too many wrong questions in the quizzes posted and in-video questions. Moreover, too complex problems were asked before being taught and no official replies to the queries in forums. Somethings are not clearly clarified. It should be free to take and submit a quiz. Why without money I cannot submit my quiz. I should only not given a certificate but should be allow to take quiz
