I did a course about 5 years ago (35mph in 30 zone), I was glad not to get the points but the course was a waste of time (in my opinion), spent half of the time listening to people airing their grievances about how unfair it was they got caught etc.
My other half has had to do one online during lockdown, she seemed to quite enjoy it, I think it would depend who your course leader is, it was a bit of a faff to set up as we didn't use zoom, skype, FaceTime etc. before this, since then we've had interviews & doctors appointment online with my daughter even doing dancing classes online. It's just the way we have to do things for a while longer at least, whether we like it or not.
We didn't inform our respective insurers on either occasion as it is not a driving conviction.
