## Exam Information in 2020

For revision purposes, here are some past exam papers and solutions:

- The 2011 exam and solutions
- The 2012 exam and solutions
- The 2019 exam will be partially discussed via life streams on Zoom; see the lecture notes in the Resources Table for solutions.

A/Prof Badziahin will be available for pre-exam consultations on the following dates:

- Tuesday November 24, 15.00-16.00; zoom link

All consultations are via Zoom. However on Tuesdays I will physically be in Carslaw C634 in case you prefer to get a consultation in person. You are also encouraged to post questions on the Ed forum.

## Class Starting Times

An important note: the computer laboratory sessions for this unit start in **Week 1**, even if
your scheduled lab session is before the first lecture. The first lab session is to introduce you
to the computer algebra package MAGMA which you will be using in subsequent lab sessions.

Lectures start in Week 1 and tutorials start in Week 2.

## Assessment

The final mark in MATH2088/2988 will be calculated as follows:

- 60%: Exam at the end of Semester 2
- 20%: Assignments (two, worth 10% each)
- 20%: Quizzes (two, worth 10% each)

## Computer Lab Resources

Most files relating to the computer labs are in the Resources Table below. Here are the instructions for downloading the student version of MAGMA to your own computer and doing the computer laboratory exercises at home.
