- This page is a only a supplement consisting of resources produced by Arun Ram for delivery by public webpage. If you are actually enrolled in the course, then you need to be fully engaging with the resources on Canvas (for Melbourne University enrolled students).
- Prof. Ram reads email but generally does not respond by email. Usually these are collated and reponses to email queries are provided in the first few minutes of lectures. That way all students can benefit from the answer to the query.
- The lectures will be live streamed and recorded via the usual Ech360/LectureCapture.

The handbook entry for this course is at https://handbook.unimelb.edu.au/view/2022/MAST10006.

The following notes are written by Arun Ram.

I like to understand the curriculum by understanding what skills are required, i.e. what problems could be asked on the exam. I do this by doing the problems that are available, from lectures, from the problem books, and the past exams, and thinking about how I can write the solutions so that, no matter which marker is marking my solution, I will get the bulk of the marks for my solution. I generally do not try to get full marks, as this is a very unpredicatble effort because it depends on too many uncontrollable parameters.

THE FOLLOWING EXMPLE SOLUTIONS ARE NOT DESIGNED TO BE AWARDED FULL MARKS. In most cases they would get the bulk of the marks for that question.
