The problem with SRS in my opinion is the inability to do many-to-one mappings. That is, a single question that builds upon your knowledge of already-learned simpler concepts by combining them together into a compound problem.

In the context of language learning this could be a sentence which tests multiple individual vocabulary items and grammatical patterns together. In the context of maths it could be using multiple techniques in sequence to solve a more complex equation.

I think this would bridge the gap between the atomic knowledge that flashcards give you and the more generalized knowledge that applied practice gives you.

AFAIK, no existing SRS is capable of this. I started working on a prototype web app that could do it but I haven't finished it yet. I plan to return to it at some point.




From a language learning perspective, I think this is accomplished via memorization of complete sentences. I am building an SRS as a side project where you memorize complete sentences instead of single vocabulary words and your response is graded by an LLM so that you don’t lose points when your answer is not quite correct or differs slightly in prompt meaning. is that what you meant? I have had good luck using this technique for memorization of grammar rather than memorization of vocabulary.
