The content is excellent, but coursera bugs and lack of support do not allow mt to give higher rating

Well readme's are written with typos - shows how much "care" has been put in to this course by Duke

I love the contents, but dealing with unknown test cases is extremely time consuming

External Grader is complicated and slow. Checking test cases is too difficult.

The test cases are tedious and not friendly for people not playing pokers

the online practice environment is not a good experience for students

Maybe the only problem was the instrucctions, but nice work

Should increase the amount of video.

That was pretty tough

too hard to code

Here's the thing, if you have experience with coding in other languages, then this is probably a good introduction to c. However, if you are new to programming beware! This is not for you. The instructions for the assignments are often vague which personally led me to a significant amount of unnecessary heartache. Moreover, they don't introduce critical concepts before throwing you at problems that are frankly sometime outside an beginner's scope. If you are new, be prepared for hours of googling in an attempt to figure out the concepts they skimmed over of failed to introduce all together. Also, the final poker testing project costs you hours while you attempt to find invisible bugs with the hints basically begin "well you should try thinking like a programmer"

the worst course course ever I enrolled. the ppe grader is just disgusting. the topic or grader is not bad ,grader complexity makes it bad.

Extremely frustrating and difficult for most people because handling Emacs is very difficult and confusing at first.

tough to under stand need more detailing for new beginners That's all

My token broke and I haven't been able to get help on it since then...

emacs editor is the worst thing in this course rest is good

i can not satisfy with this course

Bad and frustrating interface....

Not enough Instructions

I enrolled to this course with very high expectations as to the fact that I can learn the C language, but I was disappointed when I got know that the teacher(s) were in fact teaching things which were basically IQ tests. There were some parts in the teachings that were logically "broken" as well.

The teacher(s) seemed to "show off" by making very simple things extremely complex. Mind you, this course is for beginners, but you can't even pass certain assignments if you don't even have at least a slight bit of knowledge of the C language. If you were planning on learning everything from scratch, I think this course would be useless and you should look elsewhere.

Therefore, I have decided to not participate in this course due to those matters.

Too many of the assignments are "guesswork". I know if you have a methodical approach it is not guesswork. But this is now how you look for bugs, this is not how you would write tests. This is just forcing users to write lines and lines of examples without actually debugging the code. Looking at forum posts, responses from staff are not as quick as one would expect. Also there is too heavy of a focus on emacs. Nevermind the editor, use the actual terminal instead which is accessible to everyone, especially since vim is also an available editor in the environment.

I intended to take the whole specialization and I got through the first two courses when I decided that continuing is pointless. My goal was to become more proficient in C programming. Instead there was relatively little code to be written and I spent most of my time on black box testing. If I wanted a course in black box testing, that is what I would looked for. Even though I completed the first two courses, I consider them a waste of time and effort. I do not recommend them.

So disappointed in this class/specialization. The tools (programming environment) is buggy, slow, and a pain to use. Instruction is lacking in content and clarity. Had to waste massive amounts of time googling and looking up explanations on discussion boards.

I've taken over 50 Coursera courses, and this is the first specialization I quit because I just couldn't keep putting more effort into taking the course than the instructors put into making it.

Really bad course. Assignment are poorly explained, you spend more time deducting what is required than getting things done. Practice exercises requires yo to know a lot more than what is explained in the theory classes. Completing practical exercises for debugging and testing is a nightmare and provides no lessons to be applied in real life. A very poor course overall, I would not recommend it to anyone.

The grading program was horrible. I follow the instruction, make a mistake, reload the webpage, and now I couldn't emacs back to the file I just read to fix it. It keeps saying emacs is running, but when I press fg, it say bash:...... Fix this thing.
