- The examination was way too labor-intensive for the given time, even though I wrote the whole 4 hours I only managed to answer 2/3"s of the questions and not because I couldn"t answer but because there was not enough time for me to carry out all the calculations.» (No, not at all)
- the exam task was like from Mars. We did nothing similar anywhere! Big minus!» (No, not at all)
- Problems within the group effected the grade to much. » (No, not at all)
- It was a very difficult exam that for example mixed numerical method, iso-parametric transformations and Gauss points, with one-dimensional problems. That was something I hadn"t ever seen and was really confused about when that kind of method would be useful.» (To some extent)
- The final exam were to extensive. at least 6 hours examination time was necessary to solve all the problems» (To some extent)
- accually,i should do better» (To some extent)
- the exam was quite much harder than the former ones we practiced on. I know some of my friend thought so too» (To some extent)
- I expected a better grade for the final examination. We only get the final grade but no feedback, so I don"t know where I did wrong and I might have missed out.» (To some extent)
- To big focus on the raw mathematical calculations in compare with the FEM-theory» (To some extent)
- I thought the exam was quite different in comparison to the projects and practice exams. Most of the questions on the exam demanded a deeper understanding of the concepts, that we did not really have the ability to practice during the course. There did not appear to be a great variation in the level of difficult of the questions on the exam. I think the exam should be restructured to better represent the concepts presented in the lectures and in the project. » (To some extent)
- Though it felt like the final examination required more time then previous final examinations...» (Yes, definitely)

- i dont like, that we were forced to buy this particular book. It is discriminating, because without buying, the course was impossible to pass (projects)!!!» (Some extent)
- The textbook was a good aid.» (Large extent)
- The written literature were very good when it described the basics in FEM in a good and understandable way. The level of difficulty was great.Though it was diffucult to look up things in the book, in comparison with a dictionary.» (Great extent)
- The coarse book is really good and together with the lectures from Håkan you get a good knowledge!» (Great extent)
- It would be of big help if you have the money to buy it. In my opinion it was a too big dependence on the book. If you have such a big dependence, then you should offer more copies of it. Ask for example Tomas Grönsted about Gas turbine technology, how they managed it. They did it very well.» (Great extent)

- i missed stresses and strains FEM applications more. From my part of view, the heat is not interesting» (Very small)
- It is very good to know what FEM is about and its limits.» (Rather high)
- The course should remain, as it does provide fundamental concepts that are necessary for structural and building performance design. » (Rather high)

25. What should definitely be preserved to next year?

- The projects!»
- The projects»
- the system with projects are good and bonus points are good»
- The computer lab with Comsol was good. Håkan is an excelent lecturer.»
- the projects»
- work load - let them go crazy again»
- The projects»
- Everything except the computer lab»
- The course content is ok. It is very well drafted.»
- projekt arbetet och upplägget med två timmar föreläsning följt av två timmar övning»
- assignment»
- First and second assignment.»
- project!!»
- Exercises»
- The projects should be preserved, as they allow the students to grasp the concepts covered in the course. The projects also allow students to analyze realistic problems, which is beneficial for developing in depth problem solving skills.»
- the same way should be continued...»

26. What should definitely be changed to next year?

- The teaching can be slower at the beginning of the course so that the students can get into the problems more easily there after..»
- The exam should be more like the old ones, where the questions are either tricky (a lot of thinking) or labor intensive (long calculations) but never both as most where this time around.»
- less time consuming projects»
- The exersizes in the computerrooms was problematic. Partly because the whiteboards was to small, partly because the comeputers were sometimes not needed. We did not use the exersise book very much.»
- maybe a little smaller projects»
- change heat to stresses and strains... heat is not that fun!»
- Less problems at the final exam or more time!!!!!»
- The commercial software lab just felt like a waste of time»
- The computer lab»
- Mindre tyngdpunkt på projekten och högre på tentan, eftersom i nuläget blir betyget väldigt påverkat av hur gruppen har fungerat.»
- The International students are not very well versed in the use of Matlab software. In every country different programmes are used for analysis. In my country, we were taught the matrix analysis interpretative language and black box programmes, so I was not familiar with matlab at all which made the things really hard for me. I think, Chalmers should arrange some matlab courses for use in different disciplines seperately so as to enable the students with little or no matlab knowledge to come at par with rest of the students who are rather proficient in its use. Alternatively, the teacher should make the groups himself/herself by placing matlab proficient and non proficient students together in each group.»
- An introduction to MATLAB is not sufficient for most of the students. As most of the students tackle MATLAB for the first time. In this regard comprehensive lab work should be provided to the students. It would be really fruitful.»
- exorcise methods »
- I think it"s better to have an adequate time for the last chapter(isoparametric)of course. »
- Third assignment.»
- maybe more interactive lectures, since now we only rewrote what you wrote on the board, and barely had time for understanding»
- Have more exercises»
- More copies for the students or less dependence on the book. I think it doesn"t make a lot of sense, when you have in the projects just to copy the book. It was very disappointing when you worked on the project several hours, and didn"t come any further, going to ask for some help and then you just get a shocked view and a comment: "why didn"t you go in chapter xy? It"s everything written there"»
- The examination should be restructured to better represent the concepts taught and practiced in the course. Perhaps, questions with various levels of difficulty should be included. »
- if they do same...that will be good »

27. Additional comments

- Trevligt inslag med en kurs som innehåller någonting nytt! Borde kanske uppmuntra studenterna till att inte kopiera allt det som skrivs på tavlan under föreläsningarna, utan istället lyssna och förstå det som sägs. Kan tyckas självklart, men av någon anledning så gör de flesta, inklusive jag själv större delen av läsperioden, det motsatta och även om det är upp till var o en hur man lägger upp sitt pluggande, så kan det nog finnas nån vits i att ge ett litet tips om det kan påverka den kollektiva inlärningen. Boken är ju ändå ganska bra, täcker in allt och är också den man har nytta av att lära sig hitta i. Personligen tror jag de flesta vill se vad de får för resultat på de olika kursmomenten, så om det inte är alltför jobbigt så kan man ju lägga ut resultaten på hemsidan. Om man utgår ifrån att alla människors tid är lika mycket värd skulle detta vara en klar effektivitetshöjare. Annars har jag inget att klaga på. Jättebra kurs och föreläsare!»
- The exam was time consuming! I had problem to treat every problem and had to leave things behind that I actualy had knowledge about.»
- overall good an interesting»
- innehållet i föreläsningen innan abaqus labben kändes lite irrelevant »
- More labs on ABAQUS.»
