React Router course not loading exercises

Attempting to get a refresher on the React Router course but unfortunately it only loads a video instruction on the course on the right hand side, whereas the left hand side suggests that we complete the exercises. I’ve seen no previous indication that we are to perform the exercises outside of the Codecademy course in our own text editor. Was this the intended course of action we are to take or is there a panel in the exercise I am currently unable to locate to complete the challenges?
