Suggested write-up: Topics in Algebra (I.N. Herstein) — concise guide and study plan

Overview

This guide summarizes key topics from Herstein's "Topics in Algebra" (commonly used for undergraduate/early graduate algebra), highlights important theorems, typical exercise types, and gives a focused study plan with tips for mastering the material.

Herstein vs. Artin: Artin’s Algebra is considered more computational and visual, utilizing linear algebra to explain abstract concepts, whereas Herstein is more "classical" and theoretical.
