This semester I'm serving as a TA for Mathematical Concepts and Proofs. I'll put stuff on here as and when it becomes relevant.

**Recitations.** Recitations are at 8:30am in Porter Hall A20 (Section A), 9:30am in Wean Hall 8220 (Section B) and 4:30pm in Doherty Hall 1117 (Section C).

**Homework.** Homework will be collected at the beginning of recitation on the due date. *It is your responsibility to inform me if your homework is in my mailbox ahead of time*: if I find it there after recitation with no prior announcement then it will be considered late. Please use a separate sheet of paper for each question; this is because each question will be graded by a different person.

- Problem sheet 1 (source) (solutions) — due Thursday 10th September.
- Problem sheet 2 (source) (solutions) — due Thursday 17th September.
- Problem sheet 3 (source) (solutions) — due Thursday 24th September.
- Problem sheet 4 (source) — due Thursday 8th October.
- Problem sheet 5 (source) — due Thursday 15th October.

**Email.** The best way to get hold of me is by sending an email to **cnewstead-at-cmu-dot-edu**.

**Mailbox.** I have a mailbox in Wean Hall 6113, which is the best place for submitting early (or late) homework assignments.

**Office hours.** I will be in my office (Wean Hall 8205) at the following times:

**Tuesdays 11:30–12:30 and Fridays 15:30–16:30**

If you can't make the office hours and you need my help, I'm just an email away.

*Last updated on Friday 9th October.*
