This is a great course in parallel programming. The videos were very clear, summaries reinforced the video material and the programming projects and quizzes were challenging but not overwhelming.

Great course. Introduces Parallel Programming in Java in a gentle way.\n\nKudos to Professor Vivek Sarkar for simplifying complex concepts and presenting them in an elegant manner.

I enrolled in this specific course (not in the whole specialization). Later It turned out that you are not allowed to submit code if you have an unpaid subscription. Fine, I decided to pay for it. After all, someone invested his time in creating the course. Then, for some reason, I have got a subscription for the whole program, not a single course. I did not realize that and got charged the second time after the first month past. But okay, probably I did not understand the whole procedure around it.
The amount of information is very small. For 42 Euro you get few lectures and few quite basic exercises.
In most of the tasks you need o write only a couple of lines of code. The evaluation is not reliable. You can do your task right way, but it will not pass test from the first time and you are not sure if your are doing something wrong or what is the reason of the failure. Then you just resubmit the same code and after second, third or fourth time it suddenly works.
I can understand that in concurrent environment sometimes it is hard to achieve stable performance.
All together this leads to a bad experience. It is not the quality I've got used to when watching other courses here. Not worth its money. It is better to buy a book or the same amount.

I spent 6 days on this course, and I feel it is not worth the time. One of the problems is that the lectures are overly basic, and the mini projects are not challenging, at least not in a helpful way (quizzes are sometimes challenging due to some concepts not covered in the lectures at all). I guess the instructor did not really spent much time preparing the materials and assignments.

Unfortunately course designed very poorly.
While lectures generally are good, there are not enough of materials. I'm sorry to say, but programming assignments are bad. Forum is full of posts like "Grader grades the same file for 100 and 50 points". Teaching stuff reacts on this like, quote:
"Hi Anton, I may have missed it but I don't see a question in your text? Is there something I can help with?"
Yes, dear teaching stuff, you can help not only Anton, but all of us. Take a look at Parallel Programming Using Scala, here, on Coursera. Their grader is stable, and apparently there is a well-known, common way of reaching the stable state of JVM using testing frameworks. They measure performance after stable state is reached.
Also, it is not clear what is actually the topic of this course? Parallel programming? No. There is almost nothing to do with common parallel programming. No info about hardware, schedulers, operating systems, JVM. Java? Also no, there is no information on language, its specific parts, its implementation for threads, no words are said about JVM, actually JVM event wasn't mentioned. So, then, what is this course about? I may say this course "A good introduction to parallel programming".
I hope the next course in this specialization will get much better.

Practical exercises are not challenging at all. Some require changing 1 or 2 lines of code. Also, exercises are hard to test locally. Sometimes they fail on the student's machine and pass when submitted.
I don't understand why we used PCPD library, lessons should focus on Java API.

Not sure it deserves the money, YouTube has more content, but I love the prof dress
