MyUni: Teaching materials and course documentation will be posted on the MyUni website ().

This course is delivered by the following means:

• 6 Lectures of 1 hour each per week
• 2 Tutorials of 1 hour per week

A student enrolled in a 6 unit course, such as this, should expect to spend, on average 24 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).

The course content will include the following:

For Statistical Mechanics, prior to each lecture, students are expected to read the lecture notes and answer some online questions. Each lecture will then be built around responses to the online results and feedback.

To obtain a grade of Pass or better in one of these courses, a student must achieve a result of 50% or better in at least 2 of the 3 topics (Electromagnetism, Quantum Mechanics or Statistical Mechanics).

Assignments, Tests and online responses
The mix of assignments and tests will be decided at the start of the semester by negotiation with students. A combination of on-line responses, tests and summative assignments will be used during the semester to address understanding of and ability to use the course material and to provide students a benchmark for the progress in the course (40% of total course grade).

Examination
Three 2-hour exams will be used to assess knowledge and understanding of and ability to use the material (60% of total course grade).

Poor performance in assignments and tests can be partially compensated by a higher weighting of the examination in the final assessment. Online responses to questions in the Statistical Mechanics component will contribute 2% of the final result.

Submission of Assigned Work
Coversheets must be completed and attached to all submitted work. Coversheets can be obtained from the School Office (room G33 Physics) or from MyUNI. Work should be submitted via the assignment drop box at the School Office.

Extensions for Assessment Tasks
Extensions of deadlines for assessment tasks may be allowed for reasonable causes. Such situations would include compassionate and medical grounds of the severity that would justify the awarding of a replacement examination. Evidence for the grounds must be provided when an extension is requested. Students are required to apply for an extension to the Course Coordinator before the assessment task is due. Extensions will not be provided on the grounds of poor prioritising of time. 

Late submission of assessments
If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days or more late without an approved extension can only receive a maximum of 50% of the mark.
