Genomsnitt: 4.05 (bidrar till totalt genomsnitt/jämförelseindex) - The labs took some time. Otherwise the course wasn"t especially consuming.» (3)
- The 2.5 hp we got for the labs were very hard earned! It was a lot of work to write the reports. It would be better to decrease the workload of the labs and increase for example the number of lectures.» (5)
- This course is not a difficult course but the work load is nowhere near other 7.5 HP courses. You need to restructure this course!» (5)

- Quite boring to read. Hard to find a certain chapter (a more detailed table of contents - not just at the start of each chapter but in the beginning - would be good).» (2)
