In order to pass the unit, you need to obtain a total mark of at least 50%. 

Late Assessment Submission Penalty: Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark of the task) will be applied for each day a written report or presentation assessment is not submitted, up until the 7^th day (including weekends). After the 7^th day, a grade of ‘0’ will be awarded even if the assessment is submitted. The submission time for all uploaded assessments is 11:55 pm. A 1-hour grace period will be provided to students who experience a technical concern.

For any late submission of time-sensitive tasks, such as scheduled tests/exams, performance assessments/presentations, and/or scheduled practical assessments/labs, please apply for Special Consideration.

Assessments where Late Submissions will be accepted 

Project based assignment – YES, Standard Late Penalty applies 

Weekly quizzes, Class Presentation - NO, unless Special Consideration is Granted

Special Consideration

The Special Consideration Policy aims to support students who have been impacted by short-term circumstances or events that are serious, unavoidable and significantly disruptive, and which may affect their performance in assessment. If you experience circumstances or events that affect your ability to complete the assessments in this unit on time, please inform the convenor and submit a Special Consideration request through ask.mq.edu.au.

A SUMMARY ON THE INDIVIDUAL ASSESSMENTS FOR THIS UNIT:

Quizzes (15%): short quizzes will be scheduled to help students keep up with the material covered, and to help identify any problematic concepts.

Assignments (25%): two assignments relating to material covered in class will be given to test students' general understanding and problem-solving skills, as well as prepare students for the type of questions they can expect in the final exam. In each assignment, students may be asked to write short computer codes to solve parts of problems; programming a computer to answer questions that are not simple to answer in any other way is an essential skill not just in astrophysics but in virtually any profession that requires a science degree as a platform.

Class Presentations (30%): in 2 separate weeks students will be asked to read sets of notes, book pages or journal articles, or some combination of these media dealing with an astrophysical topic. Some of the material will be new to the students, and some will be from content already presented. It is not expected that students understand everything they read; however, it is expected that they be able to present questions about any aspects that they do not fully comprehend, and that these questions be in the context of those concepts that they do understand.  The ability to explain a concept in a clear fashion and according to a pre-agreed specification (level of detail, time constraints, etc.) is a key skill to be mastered by any science student, which is why this assessment task is part of the unit.

This assessment task also allows the lecturer to "flip" part of the unit. The oral sessions in which students are presenting and discussing material that has not yet been presented by the lecturer will allow the lecture time to be a far more interesting and in-depth discussion session, rather than a board presentation. The lecturer will be there to consolidate concepts and place them within a broader context.

Final Examination (30%): The final examination questions will be similar in style to those in the quizzes and assignments, but answered under controlled conditions and without the help of books. Battery or solar-powered calculators which do not have a full alphabet on the keyboard will be allowed into the examination. Calculators with text retrieval are not permitted for the final examination. 

You are expected to present yourself for the final examination at the time and place designated in the University examination timetable (http://www.timetables.mq.edu.au/).   The timetable will generally be available in draft form approximately eight weeks before the commencement of examinations, and in final form approximately four weeks before the commencement of examinations.

The only exception to not sitting the examination at the designated time is because of documented illness or unavoidable disruption. In these circumstances, you may wish to apply for Special Consideration (see ‘Special Consideration’ in this Guide).  You are advised that it is the policy of the University not to set early examinations for individuals or groups of students.   All students are expected to ensure that they are available until the end of the teaching semester, i.e. the final day of the examination period.

If you receive special consideration for the final exam, a supplementary exam will be scheduled after results are released. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.

The course will be delivered through weekly lectures and tutorial sessions. The unit will be in two parts:

1) The physical interpretation of astronomical observations, the physics of the interstellar medium, and the astrophysics of accreting gas in star formation (~6.5 weeks, lecturer Tayyaba Zafar)

2) Stellar Evolution, Pulsations, and Nucleosynthesis (~6.5 weeks, lecturer Devika Kamath)

Each part will be assessed via quizzes, oral presentations and assignments during the term, and will be approximately evenly represented in the final exam.  

Methods of Communication

Communication will be via your university email or through announcements on iLearn. Queries to the convenor can either be placed on the iLearn discussion board or sent to devika.kamath@mq.edu.au or tayyaba.zafar@mq.edu.au from your university email address.
