Ask HN: Does this math education idea make sense?

Apologies if this idea is really half-baked. Is there any sort of math curriculum for people who learned a math subject 10+ years ago and need something like a refresher, but with more foreshadowing. For example, there are many dots I connected between linear algebra and calculus, but I worry there are some dots I never connected (even though I did fine in the class). Does such a curriculum or class exist?
