> Yeah, private tutoring is the best. The custom, just-in-time curriculum that a tutor can prepare is the most efficient way to learn.

I really disagree with your choice of words here, specifically, “just-in-time”. This makes it seem like the tutor is teaching things to the student right before they need it for an exam, which is an unfortunate effect I’ve seen happen because in the long run it doesn’t really teach anything. But where a private tutor really does excel is having a better understanding of how to tailor the curriculum to the student (this includes both simplifying or making it more challenging, depending on the student and the topic).
