You have the entire code there so you can always try it in Workspaces or your own computer. Put in a set that should get just some of the courses and see if you get them.

Right now, though, your code returns as soon as it loops once. You should move your return out of the for loop.

Thanks :) I had run it on my computer but couldn't see why it would only return one thing. The indent caught me out !
