Note that the sections 53, 54, 55 in the fifth edition are moved to sections 56, 57, 58 in the sixth edition!


Problem sessions The problem sessions are held on Tuesday 10-12 and Friday 10-12, beginning January 22th . The problems will be chosen from the list of recommended exercises on the home page. All these are important, and most of them will be discussed during the problem sessions. The English spoken problem sessions are led by Jiacheng Xia and the Swedish spoken ones by Per Salberger,


Recommended exercises

The exercises below are selected from the sixth edition of Durbin’s book . The same exercises may also be found in the fifth edition and usually with the same numerotation. The exceptions are listed with a V for their numbers in the fifth edition. A star * indicates that the exercise is considered more challenging.

Examination procedures

In Chalmers Student Portal (Links to an external site.) you can read about when exams are given and what rules apply to exams at Chalmers. In addition to that, there is a schedule (Links to an external site.) when exams are given for courses at the University of Gothenburg. Before the exam, it is important that you sign up for the examination. You sign up through Ladok (Links to an external site.).  At the exam, you should be able to show valid identification. After the exam has been graded, you can see your results in Ladok.

At the annual (regular) examination: 

When it is practical, a separate review is arranged. The date of the review will be announced here on the course homepage. Anyone who can not participate in the review may thereafter retrieve and review their exam at the Mathematical Sciences Student office (Links to an external site.). Check that you have the right grades and score. Any complaints about the marking must be submitted in writing at the office, where there is a form to fill out.

At re-examination: 
Exams are reviewed and retrieved at the Mathematical Sciences Student office (Links to an external site.). Check that you have the right grades and score. Any complaints about the marking must be submitted in writing at the office, where there is a form to fill out.

Course evaluation

At the beginning of the course, at least two student representatives should have been appointed to carry out the course evaluation together with the teachers. The evaluation takes place through conversations between teachers and student representatives during the course and at a meeting after the end of the course when the survey result is discussed and a report is written. Guidelines for Course evaluation (Links to an external site.) in Chalmers student portal.
