When editing or creating a activity (or assignment) in Flint, there is a preview shown next to the tutor's settings. There, you can preview the tutor's responses to see if its behavior fits what you're looking for.

The tutor starts in "Manual" mode, which allows you to test messages yourself. To see an example of what an assignment of a specific grade looks like, click on one of the grade levels. This can help you see what changes you may need to make to the rubric or rules.

After clicking on a grade level, you can see the chat play out in real-time.
