- I wished I could"ve said to larger extend, but as the exam showed me, the available material on course web page and earlier exams did not meet up with demands set in this final exam.» (Small extent)
- The course book was fairly useless, the printouts from Cremona were all useful. The additional reading linked from the website was interesting, but did not help me that much with the course.» (Some extent)

- In extension to earlier comment, since the course web page and available resources didn"t match the expectations you set in exam, it can"t be viewed as well.» (Rather badly)

Good»8 34%
Excellent»2 8%

Genomsnitt: 3.13

- OS should be interesting, the lecture weren"t and the course was very basic» (Poor)
- Bad and uninspiring lectures and slides! » (Poor)
- Course contents are mostly interesting, however many things are not directly related to operating systems.» (Fair)
- It"s a double edged blade really, that the context of the course seem to change to much to coup with changes in computer systems. It great it"s up-to-date, what wasn"t great was that you were left in the blind on the exam if you"d studied old exams since they don"t reflect new material and learn stuff that"s been cut.» (Adequate)
- The content of the course was good and the labs were okay. But the quality of the lectures need to be improved.» (Adequate)
- The labs was hard, but good. The teachers need to step up.» (Good)

15. What should definitely be preserved to next year?

- The two labs are good (but the shell parser is awful). The lectures about Processes, Threads, UNIX, Memory Management, File Systems, Scheduling and Virtual Machines»
- the teaching assistant maybe.»
- Lab»
- lab»
- Labs, they are very good hands on experience.»
- the labs were ok»
- the shell lab»
- Not much.»

16. What should definitely be changed to next year?

- Remove the Disk lecture (what does disks have to do with the OS apart from the driver), and the lectures about Distributed stuff. Info about deadlocks and synchronization should definately be shorter (you learn all of that in other courses)»
- the two lecturers,both of them are really boring.they only help sleep during the 90 minutes.however the three teaching assistant are fairly well.»
- Some projector film slide are not fully available in PDF format which we can download from the course home page.»
- nothing»
- nothing in particular»
- better slides/more effort put into lectures»
- The documentation for the OSP system was inadequate. It was inprecise and lacking.»
- If the course is supposed to be held in English the lecturers need to hold a higher standard in their presentations.»
- the teachers, and the lab supervisors :/ Nothing personal, this aint much worse than usual, but would be nice with people who is active in the OS field, make the course harder, the lecturers will probably feel like they are doing something more important than just giving the student"s another 7.5 for reading some book.»
- The quality of the lectures.»
- Slides and course content in general! What has RAID go to do with operating systems anyway? More focus on OS specifics and not on things like RAID!»
- Faster lab correction, took over two weeks to get a lab corrected.»
- The teachers! »

17. Additional comments

- this is the worst course ever i"ve been to at chalmers!!!it"s a nightmare.»
- This course covers a large range of topic, we have to keep the pace at 3 lectures per week. some content of the lecture is hard to be found in a specific chapters in the Course book. maybe too many topics in 7 weeks.»
- interesting course!»
- Expected grade: 5»
