In what order should I remember/learn math?

Question

Mathematics

I started reading SICR and realized that I need to remember mathematics and learn what I did not know.
It so happened that he studied in college, did not go to university. There was a bit of a tower in college, but I don’t remember almost anything anymore.
In what order should I start remembering/learning? What books/websites are best for this? (Found some interesting courses on Stepic and Coursera)

From the search, I liked this site more. Somewhat critical introductory article, but written from the heart: www.mathprofi.ru/matematika_dlya_chainikov.html
