From my experience the knowledge of a university course topic should be a reasonable conpromise between full understanding of all concept in detail (which could require too much time) and the study of the key concept, and the capability of apply it. I often found in university course (in Italy) an excess of theory and detail on all the topic and subtopics, and a poor teaching to apply the key concepts that are the ones you would use in practice. (Even if the test require also the capability to practically apply concept)
