Course is great although there are mistakes that haven't been fixed for some time now. I would recommend regardless of the mistakes though.

The course is pretty good. One problem is that the answers in some questions are wrong and autograder hasn't fixed that.

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.
