Listening to the lectures and reading the material is not enough to get more than 20-40% of the max score in some of the tests. The reviewers can give lower scores even if the assignment has been done correctly, just because why not, Coursera couldn't care less. References/paths are often out-of-date. Neither the Android app, nor the web interface displays the correct answers.

too much into software , very few practical embedded system knowledge

All are basics only. . . and its not a hands on training

The lecture videos are pretty decent, but the quizes, tests, and assignments are brutal with confusing instructions, little to no examples or relevant resources for help. The entire course is littered with typos, spelling errors, etc. that need to be reviewed. The Final Assignment did not provide a solution to refer to after submitting it. I know I didn't do it correctly, but somehow I passed that last assignment and the entire course. This course is such a joke. I can see now why employers don't take Coursera certificates seriously. Seems like a money grab without any effort to actually help the students learn the material effectively. Such a waste of my time and money. Lost faith in Coursera and am now exploring alternative options like Udemy, which seem to be higher quality for cheaper.

The course material is shoddy, the assignments ambiguous and some of the provided test code in the final assignment contain errors. 4 days after reporting the errors/asking for clarification (nothing in the assignment said to expect or fix errors) I had not received any response from the instructor or a moderator.

My employer paid for a plus subscription for several work related classes, I took this as a curiosity since it was effectively 'free to me' having completed the planned courses. Had I paid for it out of my own pocket I'd be asking for a refund as the class seems to have been dumped on Coursera and then abandoned.

I can assure you that if you are a beginner and thinking to get knowledge about the subject and learn something useful than u are at a very wrong place. If you are from India just go to NPTEL channel on youtube and learn from there because this course is a package of unnecessary high-level things without any explanation.

the professor will explain some topics well like memory management but will not explain about the practical codes (which are useless) he will write not even a bit.

So don't waste ur time just enrol in some other course or as mentioned learn on youtube.

There is no way to unenroll from this course. No way to contact anyone. The help center mentions an outdated method that no longer works. Do not enroll in a course here, unless you are certain that it's a course you want to take. The only way I have found is to cancel my subscription.
