- Martins lectures was really well weighted to find a good opening for reading the book. I stopped going to the excersice classes after a while since I felt I did not learn any extra from these occations. The lecture notes was sufficient.» (75%)
- the lectures helped alot » (100%)

- Resonable, but still quite a lot of work to do!» (Yes, the goals seem reasonable)
- Perhaps though, it would be better to have some of the cosmology moved to the astroparticle physics course (which could be called Cosmology, really). It is a bit stressed towards the end as it is now.» (Yes, the goals seem reasonable)

- the question 6 took way to much time to solve and the work wasnt directly related to the course» (Appropriate)
- However, some people tended to copy solutions which could be frustrating. The home exam deadline being moved also seemed somewhat unfair.» (Appropriate)
- They took alot of time, but were manageable. Havnt got any results yet though.» (Appropriate)
- The home assignments took almost a week each, without intruding on the lectures, which is doable. I spent almost two hours full time on the home exam, partly because the Gödel problem just didn"t want to come out right at first. It has been a demanding examination, certainly.» (Appropriate)
- As I expected, alot of time spent, though it was self chosen to do well. The Gödel metric was fun.» (Appropriate)
- The two home assignements were on a good level of difficulty. I found the take home exam to be rather difficult with long and tedious calulations.» (Too difficult)

- Indeed high but again thats normal.» (High)
- Took 3 courses, so no wonder! =)» (Too high)

Genomsnitt: 4.57

- A bit too much material. The subject is pretty deep and some disucssions would have been enlightening,» (Good)
- Very interesting subject!» (Excellent)
- Very good and interesting course! Martin is a very good lecturer. The excercise classes were not that good.» (Excellent)
- This course was exactly as great as I expected.» (Excellent)
- Very interesting, educational course and inspiring lecturer!» (Excellent)
- Interesting insight in Einstein"s Theory of General Relativity!» (Excellent)

16. What should be preserved to next year?

- About everything! »
- The form of the home exam and the hand-ins. I feel I learn much more from this type of examination than a regular exam.»
- Hand-in problems»
- Handins were good for learning. But we need faster feedback. Nobody knows whether their solutions were correct or not.»
- Since Martin is leaving, I would say Christian"s exercise classes!»
- I think it was a quite well-composed course in terms of contents and order, so I suggest not making too big changes there.»
- Martin hopefully.»

17. What should be changed to next year?

- Shorter home exam, would have been nicer to have christmas holiday... »
- The excesrcise classes were sometimes very much out of sync with the lectures some times.»
- I would have liked the result on the home assignments before the exam»
- Maybe consider having a slightly shorter home exam, thus allowing for a possibility of Christmas vacation.»
- Maybe the cosmology part can be dropped since it is so small anyway and that material can be put into astroparticle physics (or what the follow up course is called)»
- Perhaps adding or at least recommending some more litterature than Weinberg. I had a look in a book called "Relativity, Gravitation and Cosmology" by Robert J.A. Lambourne (Cambridge) was very clear and easy to read for a beginner.»
- I think one could consider moving some of the cosmology part - particularly development of the universe, consider dark energy as a scalar field - to the cosmology course. The bit about symmetric spaces, derivation of FRW metric should stay though, as Weinberg"s Cosmology takes that as a given and continues from there. I have heard that the course is supposed to be moved to the third quarter, which would imply a need for a less heavy examination. (You just cannot have a two week home exam when the next study period is just beyond the weekend.)»
- Im not sure if there is any need for change. Though it would be appreciated if the hand ins were to corrected before the home exam and hence could give a hint of how well you are doing and how you should take on the home exam.»

18. Additional comments

- Perhaps the best and most interesting course I have taken.»
- Einstein rocks.»
