Some other sources:
- discmath.ch has some good chapters on Algebra.
- Abstract Algebra by Thomas W. Judson is a great further reading if you like Algebra. The proofs in there are good practice + intuition.
- Categroy Theory Script can give you another perspective on some topics. They use different notation than this course, so proceed with caution!
Exercise Sheet Recommendations
Do all of the exercises, all of them are useful. It is not necessary to do the exam exercises already if you don’t really have time for them. Make sure you are exact and formal on the other ones!
