**Summary:**Roadmap of most useful math to learn to better understand cosmology

I just watched ~20 hours of a serie of videos about cosmology, which stayed at a conceptual level for easier understanding (= minimal math).

I understood about 98% of it and now have a decent understanding of Special/General Relativity, Quantum Mechanics, the Standard Model and some more speculative stuff about Quantum Gravity.

This said, it was frustrating to be quite lost every time the guy was explaining even the most basic math behind it all.

Assuming I'm still quite comfortable with basic algebra (I also studied derivative, integral, etc in high school, but forgot most of it), I'm wondering what parts of math I should have a look at to get at least a better understanding of the math used in astrophyics.

My question is double:

- What would be a natural roadmap from here on (still focusing on astrophysics and cosmology), either in order of usefulness or in order of natural learning

- Any resources (books, videos,...) you recommend for this

Thanks
