- A very valuable course that has tought me alot of new physics. (Very positive)
- It's a very nice theory and it is very cool to learn how to do practical calculations about particle interactions. Even though I've been quite stressed for much of the time, I really enjoyed the course. (Very positive)
- Very interesting subject. (Very positive)
- It was the physics course which for me have been the most fun, to at last apply and combine special relativity and quantum mechanics to see what comes out. Very many new things. (Very positive)
- Well the subject is very difficult and the teacher is not very self-confident, plus the book is quite incomplete in that it does provide the students with full explanations and you can spend quite some time alone to derive formulae that are not demonstrated in the book of the teacher either. (Neutral - no opinion)

- The subject itself is not easy but is explained well during the lectures. Aiming for a good grade, this was probably the most difficult course I have taken so far. I don't think it is too hard to just pass the course though. (Very difficult)
- Probably the most difficult course I have ever been able to go to. (Very difficult)
- In comparison to others KTH physics course, one of the most difficult. But considering the topic, the difficulty seems reasonable to me. (Very difficult)
- Grasping the material is significantly harder than solving the problems and passing the exam. (Quite difficult)
- Quite difficult because I had 3 other courses at the same time. (Quite difficult)

Has there been much overlap with other courses?

Far too much overlap0 0%
Some overlap, but it was useful to go over the topics again8 53%
Mostly unnecessary overlap1 6%
No overlap6 40%

- At no point did I feel the course was too slowly progressing :P (Some overlap, but it was useful to go over the topics again)
- Very little in the beginning about relativity and tensors, the rest was completely new which was very refreshing. (Some overlap, but it was useful to go over the topics again)
- The QFT part of the course was completely new. I hadn't learned about the K-G or Dirac equation in a structured manner before either so the entire course was essentially new. The first lecture tied in well with previous courses. (No overlap)
- That was the only class I was following appart from my master thesis, so of course no overlap. (No overlap)

- They were relevant though -except maybe number 4 on the last homework. That excercise felt more like a purely algebraic and very time consuming challange that did not do a very good job to test our knowledge of the course. (Very difficult)
- The problems feel relevant to the course and are of varying difficulty. Solving the harder ones requires a fair understanding of the subject and I found myself often searching for additional reading material, which is good. For a course such as this I think homework problems are the superior examination form. (Difficult)
- Most of the problems were standard problems, but some (like solving the KG for an exponential i think it was) were very hard. (Difficult)
- and the third one very difficult (Difficult)
- I think they were good as to get a feel for the subject and to learn the practical counting and enhancing the interpretation bit; to stop and think over what a quantised field really represents, eg. (Difficult)
- Well, it depends on the problems, so my answer is more an average between "average" and "very difficult". (Difficult)
- Some of the problems where much easier and much shorter than others. (Average)
- Quite demanding but very useful to digest all the concepts (Average)

- I didn't go to the oral examination (?)
- I think the oral examination was not as harsh as I expected - mostly asking for facts and basic knowledge (I anticipated having to prove stuff on the white board. I was very pleasantly surprised I didn't have to) (Average)
- It was nice to talk with the lecturer about one's knowledge and to get some feedback. (Average)
- For someone who has seriously and regularly studied the course. (Average)
- I think the oral examination was good. For a simple pass/fail exam the difficulty is good. One could consider adding the chance to earn additional points by answering more difficult questions or explaining previous homework problems. (Easy)
- I was surprised by how low the requirements for passing the oral exam where. (Very easy)

- The book is a good summary and very valuable when solving the problems. To get a good understanding of the physics I found that additional reading was required. (Good)
- I think the book is good, but it would be easier to follow if there were more large worked examples. (Good)
- For certain parts of the courses, eg for remormalization, I think that the courses book was not sufficient and I had to refer to an other book. (Good)
- I liked the book very much. Short and effective. Maybe there could have been a few more physical interpretations of some certain things, e.g. Non-abelian field tensor and perhaps some more illustrative worked examples, to easily grasp the use of the theory; such as the example at the end of the chapter on LSZ-formalism. (Good)
- I missed a more rigorous and thorough treatment in general. The book often felt rather non-explanatory and sometimes it felt as if it was trying to hide what/the fact that something was difficult. I would in particular also have liked a more practical view of the Feynman diagrams as well as a clearer link to the invariant matrix element. There was however a good and well distributed supply of recommendations for additional reading that I liked. (Average)
- The book is so expensive, I don't understand why Tommy doesn't give us a pdf version of it, or a KTH-compendium - students are not "buyers" ! (Average)
- The book is too brief. (Average)
- The book is really close to the lecture, it is logical. I personally think that the material is well fitted for lectures but less efficient as a written reference. (Average)
- The course book contains many lingual errors and anomalies. (Poor)

- All positive: good lecturer, knows the subject, answers questions well, clear writing on the blackboard. (Very good)
- The lecturer was very good and I personally very much like the classical blackboard tutorials. (Very good)
- I didn't attend many, but the ones I did attend were nice. (Good)
- A bit confused at times when thecnical details in calculations went wrong. (Good)
- The teacher would basically repeat what is already in its book with no further explanations, not really worth it. (Average)

Please, enter any further comments on the course below.

- It would be better to let this course have more points, longer time and more time spent on each chapter (like spending a few weeks only on solving single particle KG/Dirac for specific potentials or useful approximations, more time spent on the group theoretical framework of relativity and lie algebras and so forth)
- A bit dense, the 1 period and a half period length of last year would have been appreciated.
- Tio much focus on math and not enough focus on physical concepts, especially in the book which is Hood except for that...
- I don't see anything to change, the course is almost perfect like this
- I think I learn more from solving a lot of small problems rather than solving a few complicated ones.
- I think the course overall was very good and interesting, I'm glad I chose it. However i think it was a bit stressful to have the oral examination before the course ended with the assignments, at least for me. But otherwise I'm very pleased.

- It is a good thing to do a course evaluation on the internet because the institution won't have to do all the paperwork. Also it is easy to fill this out whenever one has time. (Very positive)
- An online questionare seems to be the only reasonable option. (Positive)
- It is good. (Positive)
