Yep! This kid has a super power! I don't understand why this sort of learning to learn isn't taught in schools - I only discovered anki and even spaced repetition at age 35, and I could really have used it at school!

I think the workaround that I came up with myself was to work through a large amount of derivations (maths, physics and chemistry) and try to note the common stuff and prepared shorter and shorter versions of the notes from which I could rapidly reconstruct everything else.

In hindsight, I was training an autoencoder.
