Interesting. I have used multiple different approaches with Anki. Last year I had to learn all pre-university math to enter uni, and I decided to use Anki which worked out pretty well. For a lot of the problems it's about remembering what steps to take in general. So I put in practice problems so I could remember the steps. The numbers don't matter, they could've been anything.

I also tend to put in definitions, rules, theorems, standard and harder derivatives and primitives.
Now I'm in uni and I used Anki for learning linear algebra, I mostly te...
To me it seems that the world couldn't have turned out any other way, but it's useful to think about it as if it could in the moment. The decision you're ultimately making after careful consideration is the one you'd make, no matter how many times you'd rewind time. Having the ability to make a choice doesn't oppose determinism and its ramifications. With the right input you'll produce the right output.
Could you give an example of how you'd make a Fermi estimation of a program's runtime?
