A decent amount of typos. A couple tests ask to write a program but don't tell everything being tested, or the example output doesn't show everything being tested (print statements for example) or the test is actually testing incorrectly (impossible processing times/ incorrect math), or the test says to write one type of program but then tests a different one (says to write first come first serve, but output says your shortest job first code is wrong, and you're left wondering what it's testing), the multilevel feedback queue test is wrong in so many ways I don't know where to start, also you only get three tries to compensate for these problems or retake the entire test having to write several programs, which will ingrain the information better, I guess is a positive? There's more problems but I'll stop there. All that said, the actual content in the lessons is good and educational, it just needs massive corrections.

This course is less about operating system concepts and more about programming in C. It's also filled with spelling and grammatical errors. The interactive shell and IDE are very cool when they work well, but they don't always work well. The summative assessments don't fully spell out what they expect you to do; for example the last assessment doesn't tell you that it wants you to use malloc() and free(), nor does it tell you that you must check for properly-allocated memory, but you'll fail the assessment if you don't do these things. I don't recommend taking this course if you either: a) don't know C; or b) aren't interested in learning C

The assessments are buggy, the slides have annoying animations that are harder to read than static diagrams, and the course uses a nonstandard interface that constantly opens new tabs and can't be used on mobile devices.

Graded assessment of module 2 is very unpredictable please be aware of it

No es lo que esperaba del curso !!!
