+This exercise could benefit from the following rules in the [analyzer]:
+
+- `actionable`: If the student used a loop in the `tryFinishTrack()` method, encourage it to explore a different approach.
+
+If the solution does not receive any of the above feedback, it must be exemplar.
+Leave a `celebratory` comment to celebrate the success!
