In the code challenge, apparently not all of the topics supplied to the function needs to overlap with a certain course in order to be required to be returned from the function. Here is my code which completed the challenge:

def covers(topics_set):
    output = []
    for course, topics in COURSES.items():
        if topics_set & topics:
            output.append(course)
    return output
