Thanks for giving it a whirl!

I agree that the current grading is a bit harsh -- the rubric we're using in this demo is fairly rudimentary. What we've seen be more helpful is a range of grades along the lines of correct / correct but unhelpful / correct but incomplete / incorrect. This somewhat depends on individual use cases though.

Let me know what questions generated you thought could be more complex! We're always working on improving our ability to explore the knowledge space for challenging questions.
