Hi Kathryn and Beth,
Thanks for posting about this. The last thing that we want to do is frustrate teachers, and of course it’s frustrating to have code in an exemplar that’s not reasonable for students (or even teachers!) to recognize.
If you see something like that, please consider it a “bug” in the course, and report it through the “Report a Bug” link in drop down menu on the top right of the page. It sometimes takes a few days for changes to show up on the site, but it’s a top priority for us to fix things to make it easier for teachers.
We really appreciate all the hard work that teachers are doing, both in teaching a new course, and in helping us to make it better.
