Maybe give the tutor some personality or persona (having it speak as the instructor). I’m probably off base with that suggestion, though.

Again, very cool idea. I'm going to try some of the nuclear courses later this week.

Best of luck!

Please don't, or at least don't without a looooooooooot of behind-closed-doors trial and error. There are few things more off-putting then an AI try-hard "i am a quirky hooman with quirky hooman personality traits".
