Revision
R1,

R3,
E1 (notes, boards),
E2 (notes, boards),
E3 (boards),
E4 (boards).

The proof of last proposition of Lecture 16 (pp. 63-64 on visualiser slides), the proof of the
first theorem of Lecture 17 (p. 65) and the proof of the Proposition on finding roots of
Lecture 18 (p.69) are non-examinable, due to adverse weather conditions.
You just need to know the statements.

Similarly, you do not need to know the proofs for which it is either
(a) stated that you don't need to know them (those using axiom of choice, and the
ones in the last section on ruler and compass constructions), or
(b) those that are omitted in the lecture notes/lectures (like the proofs of the
2nd/3rd isomorphism theorems).

### Exercises & assigned homework

There are 10 exercise sheets for this course. Each one contains one assigned question
that has to be handed in on **Thursday** the week after the sheet is set (either
after the Thursday lecture or in the Algebra 2 box) by **4pm**.
Your question will be marked, and the 10 set questions count towards the final grade.
Late homework is not marked.
