Hi Alex

COURSES is a dictionary, where each key is a course, and the corresponding value is a set of topics that the course covers. You may iterate over the dictionary and perform whatever set math you would like on the set of topics.

def covers(topics):
    results = []
    for course, course_topics in COURSES.items():
         # course_topics is the set which you can use for this question
    return results
