Kendall, To access the set of course topics in the COURSE dictionary, you need to loop only through the key (course name). Then you can do an intersection with the passed set_of_topics, building up your covered course list if the intersection is not empty. Hope this helps!

def covers(set_of_topics):
    co = []
    for k in COURSES:
        v = COURSES[k]
        if set_of_topics.intersection(v):
            co.append(k)
    print(co)
