We have posted new versions of the exam set and their solutions on the "exams" page on the left. The updates are relatively small and do not really change the final answer on any problems. So, if you have already looked through the solutions, there is no need to do so again. However, if you haven't yet, please look at the new, updated version.
The exam set and suggested solutions are now online here. Thanks for your work and attention this semester, hope you have a chance to enjoy the warm summer weather before (or while) preparing for any further exams!
