> So, you havent really learned anything from any teacher if you could not do it again without them?

Well, yes?

What do you think "learning" means? If you cannot do something without the teacher, you haven't learned that thing.

I mean...yeah?

If your child says they've learned their multiplication tables but they can't actually multiply any numbers you give them do they actually know how to do multiplication? I would say no.

Yes.

Yes that's exactly right.

That would be the definition of learning something, yes.
