Under Main Navigation > "Course Search" you can search for keywords. These can be teacher names or words in course names or course descriptions. The entire Moodle instance is searched.
In order to distinguish between courses with the same name, pay attention to the teachers and semester names given. You can also see which semester the course is in by clicking on the course name above.
For LSF-linked courses, you will also find the link to the Moodle room on the course page in LSF.
If you want to find a course in which you are already enrolled, you can use the course search on the page Main Navigation > My Start Page.
In the course overview on "My start page" you can filter the courses by "past", "current", "future" or "favourites". The time classification refers to a setting that teachers configure in the course and does not have to correspond to the current semester period.
