This sounds very similar to the system behind http://mathacademy.com . You follow a graph of skills and dependencies and because you always have the necessary prerequisites it is always doable.

Their team of mathematicians have created a curriculum from k-12 to a bachelors in mathematics.

Mathacademy looks interesting but FYI for everyone else, this user only has 5 comments in their history and 4 are advertising mathacademy

It's also $49/mo with no preview.

Yeah, this is cool and similar to the end state I have in mind. The main difference is that I am not trying to create the curriculum/exercises. I am just creating flaschards that say "Solve exercise x.y.z in that textbook". Plus the whole free-software angle and being able to share the material as text files.

The math thing is just a side project at the moment to try to see how it works for other fields. I am primarily using this for music. I was hoping something like this existed already, but all the solutions are either very specialized like this one or do not support dependencies as a core feature, like Anki. Had Anki supported something like this, I wouldn't have needed to make my own thing.

It would be nice to simply include support for dependency tracking in existing flashcard software. Unfortunately, the most commonly used flashcard software, viz. Anki, has not been adding such features. I can only assume that the project is very lightly maintained and/or working on paying down technical debt - new innovative features don't seem to be a priority.

Kahn Academy has a similar graph and plenty of gamified experiences, but its a non-profit. $50 a month is expensive.

This looks great. My son uses “beast academy” from Art of Problem Solving (https://beastacademy.com/), which is fantastic. But mathacademy looks like it might be a good competitor at the post year 6 level.

It would probably be best to use the AoPS books in conjunction with the site as a supplement.

I'm in the market for something like this but $49/mo is absurd, even though it's supposedly discounted from 79/99. Way too high

How is it better than the Khan Academy courses?

It's not K-12; it starts at 4th grade, according to the site.
