-<h2>Code review</h2>
-
-<p>
-  Code reviewing is a process in which a course teacher or an assistant goes over the code in a submitted answer and reviews it, providing comments for the students. Some exercises require a codereview to be completed. Students can also manually request a code review.
-</p>
-<p>
-  If there are any unreviewed requests, the course front page has a link 'n code view requested'. You can start the review process by clicking on that link. Furthermore, the submission list on the bottom of the page shows whether each submission requires a review.
