The question is clear in the title. Also, if it matters, I’m using this as a title to my notes, obviously. I’m currently going with my guts and have written “to.” Please provide examples/counter-examples to back your answer. Thank you.
Edit: From comments below it seems like “on” is probably wrong in the context. “Notes on a Scandal” is alright but the “notes” I’m referring to are not “about the booklet” but rather have been taken out of the booklet with modifications. So, “Follow-up notes on the quiz booklet” feels wrong. But no one is sure yet. Also notice the article “the”. Hopefully, this clarifies the context.
