- The webpage was finished, a lecture plan, lecture notes, assignments, old exams, all of it was up *before* the course started. I have never seen this on Chalmers before. And solutions (understandable and readable!) to this years exam was posted the same day! If all teachers at CS (or indeed Chalmers) would take a weekend course in course administration for Björn, life as a student would be a lot easier...» (?)
- Other courses should look at how this course handheld this, exceptional! » (Very well)
- Great job!» (Very well)
- simple and fair» (Very well)
- Best course page so far» (Very well)
- I especially liked the online labs. The teaching assistants also quickly replied to questions via email.» (Very well)

- I had problems debugging my programming assignment and got very poor feedback as to why it did not work. I e-mailed my assigned grader and asked more specifically what was going wrong inside my methods and the reply i got was simply that "he didn"t know". This just seems lazy to me since he should have known, and if he didn"t he had (I assume) multiple working variants of the lab he could compare it to to see where mine differed. The same grader also gave me returns for using my own notation and for describing a message exchange with words instead of with notation. Note that this was a very easy question that only required the sending of 2 messages. This course was the first time, in my 5 years at Chalmer"s, that I have failed the lab part of a course. » (Very poor)
- Only weak point of the course imo, that there were few organized opportunites for asking questions. Michal does a really good job at giving feedback on the handin assignments (though it could have been faster) but I happen to know he is also an awesome "handledare" and I"d have liked to see more of that.» (Rather poor)
- The course assistants should give better hints and explanations when an assignment is rejected. Not just "wrong on question 2" or something like that.» (Rather poor)
- The course tutors where incredible! Super-helpful guys!» (Very good)
- BvS is very forthcoming and helpful when presented with questions.» (Very good)

- I liked the fact that it was more about learning and understanding the concepts, rather than having to memorize too many details.» (Good)
- Interesting material!» (Good)
- maybe a bit easy? or is the teaching so good that I find it easy, hard to tell.» (Good)
- Very fun and interesting course overall» (Good)
- Assignments are quite easy and require no deeper understanding of the subject.» (Good)
- Best course ever.» (Excellent)
- Very good teacher/examinator!» (Excellent)
- Epic lectures! interesting topcis =)» (Excellent)
- Very well structured course. Laborations are top notch.» (Excellent)

15. What should definitely be preserved to next year?

- Björn, Michal, web page, book, assignments except #3, ...»
- The assignments were a lot easier than I expected, but they definitely helped in gaining a better understanding of the material. Unfortunately I did not have time to do any of the exercises myself, but I did learn a lot from the exercise sessions as well.»
- The assignments were a lot of fun and Björn"s presentation slides are nice... so keep them.»
- Clear exampels, definitions and good questions for the exam. »
- All of it»
- Exercise sessions were really good since it didn"t linger on the trivial stuff (which is good, in contrast to some other courses). Assignments were good, albeit too easy in some regards (elliptic curves & protocols in particular).»
- Björn von Sydow»
- Assignments»
- Great administration and interesting classes! »
- The teacher!»
- No comments. »
- I think this course is well made, maybe it should be harder? or is it just that good?»
- The course-layout and lectures.»
- the first homework was nice»
- The assignments, since I"m going to need to do them again.»
- Most of the labs were very good»
- All the assignments»
- Slides, labs and the style of the exam.»

16. What should definitely be changed to next year?

- More "handledningstillfällen", change the ECC assignment to be a little less confusing»
- On the problem sessions I would have liked it if Björn took a little more time on each exercise and did proper notes on the black board, not just scribbling down some keywords.»
- Nothing I can think of»
- Can"t think of anything, maby the correction of the assignments could be done faster»
- The materials are great and up to date. »
- don"t know.»
- The first hand-in should perhaps be put a little later in the course.»
- I got a fail on many assignments multiple times and the teacher just said it was wrong, not what was wrong. VERY BAD. It was also quite inconsistent as some students passed with the same answers as some who failed.»
- Exam too easy»
- The elliptic curve crypto lab was not good.. I did not learn much from it.»
- .»
- Covering actual cryptographic libraries along with best practices on how to use them in actual applications. Possibly including an assignment on constructing a rudimentary system that needs to use basic cryptographic primitives.»
- Maybe try to not schedule 2 lectures at 8am each week (this is why i never attended the lecture itself).»

17. Additional comments

- Awesome subject.»
- There"s too much content in this course, way too much. That and I think there"s a dissonance between the exam and the content of the lectures, the exam is focused on problem solving but the lectures are more about learning facts.»
- -»
- This course helped me to think the subject matter and worked individually. It"s creative course for me. I had to understand the subject matters not to memoriz. Thanks .»
- Nice cource :)»
- The lecturer is very good :)»
- Thank you for the interesting time.»
- The assignments were very good.»
