Looking for i7 source of a tutoring system

I am looking for i7 sourcecode of a tutoring system.

  1. The player is a student…

2a) the parser is the voice of the teacher
or
2b) a Person NPC is a Teacher

  1. explains a topic

  2. quizzes student on topic

I’m not sure if Inform 7 would be the best platform for this. But you should look at the extension Questions, which I believe was written by Michael Callaghan.
