some problems have error which are not corrected

it's a good experience learning online .Thanks

there was some mistakes in the quizzes

Lots of mistakes in practice quiz

too many problem with the quiz

good explantion by George Tech

No proper mentoring

Update is needed

Muy dificil

excellent

Before all of the negative stuff, I would like to say that I learned a lot from this course. I just believe that it could have been made a lot more error-free and easier. Here are my complaints:

*There were a ton of errors in the practice problems (both in the questions and the accepted answers).

*Some questions (both in the practice problems and on quizzes) required outside knowledge (other than basic calculus physics, which are supposed to be the only prerequisites).

*Some of the subjects covered need more explanation than what is given in the limited lessons.

Overall, I would not recommend this course to anyone without basic circuit analysis experience and the ability to spend extra time researching to fill in the gaps left by the lessons. I'm sure that there are better courses for beginners (e.x. maybe MIT OpenCourseWare).

Lecture content that must be combined with watching many sample problems to piece stuff together. I did appreciate the example problem presentation by the additional professors. Very, very sloppy work by the staff on exercises and quizzes in terms of typos, ambiguous presentation, out-of-order assessment (problem given in the wrong week before the subject matter was presented), and clearly correct answers not being accepted by the auto-grader. I didn't want to walk away from the course without completing so I spent many hours banging my head against issues with the quizzes, going back and forth between forums, and in some cases finally guessing to figure out what the problem author meant to write. Do yourself a favor and audit this one. Find some problems to work on from a different source.

Some very good explanatory videos, however, there are two serious problems. One problem is sequencing: students are expected to solve problems before the material is introduced in the videos. An even more serious problem is that the autograder erroneously marks correct answers as incorrect for many questions. The discussion group is full of examples but, even after five years, the course authors have not fixed any of the errors, which are many in number and serious in nature.

Course provides you basics, I give it that. The flavour isn't the best, but that's not the problem. The problem is there are a lot of mistakes during the course: in videos, practice quizzes, including grading tests too! Hours and hours of wasted time trying to solve a problem, solve it right and get the "answer is not correct" form the makers. Don't bother reporting those mistakes. Many have tried, me too, no reaction from the makers of this course.

The main content is OK, but the course doesn't seem to have been carefully curated at all. Several problems have the wrong answer key, week 1 had questions only answerable with knowledge from week 2, week 2 sample problems included a ton of problems on components not covered at all in the class (op amps), etc. Forums are basically abandoned as far as I can tell.

The content is good but the exercises and quizzes are full of mistakes. This makes the learning process extremely frustrating. You end up going to the forums almost every time to try to understand if there's a problem with your calculations or if it's a problem with the grader. In most cases, it's the grader.

Various issues with the course. practice problems don't always align with the lectures. Copious typos and errors in the problems. Course creators seem very lazy. Completely unsupported. Content was good and helpful for refreshers.

There are no course materials, only videos: that's not enough. There are no corrections for the quizzes, which is very frustrating when you don't succeed. All in all, this MOOC is pretty passable.

I have rated this course with 2 stars since my experience was not too good with this course.

there are many mistakes in the practice problems please take care of them.

course structure is good and worth a 5 rating but I am rating it 2 only because the mentors are not active at forum and grader is found faulty at times

The course has many errors that haven't been corrected in years, and the forums have zero support from the course staff.

Too many error in the grader. You're on your own because no one helps you.

lots of issues on problems

Assignments are very tough.

I am posting a rating of One Star to hopefully draw the attention of anyone responsible for posting the course content.

There are some mistakes inherent in the grading, (i.e. the robotic graders), for both the practice problems and the end-of-chapter quizzes. Multiple learners in the community have noted these and posted such in the discussion forums, yet there has been no response from the Instructors and/or Administration responsible for the MOOC. Also, in having gone often to the discussioon forums where we are promised to encounter the Instructors, I cannot recall having encountered any Instructors for the discussion forums I have visited. Many of the Learners seem to be performing the job of the Instructors.

Also, if I may offer observation. the instructional videos tend to be very brief, and usually give a problem and then jump to the solution without showing some of the work involved to arrive at the answer. Contrary to the lab videos which are quite lenghty, yet spend idle time showing how to physically attach a component to a circuit on a breadboard.
