- Al Cuoco & Joseph J. Rotman, Learning Modern Algebra, MAA Textbooks, 2013.
- Frederick M. Goodman, Algebra: Abstract and Concrete, edition 2.6.

Please feel free to download and print these notes for your convenience.

Disclaimer: my notes are meant to be a toolbox while doing proofs and studying/practicing the course in general. There may contain typos or mistakes. Please feel free to let me know if you find any errors!
