Other Information

Assessment Information

• To pass the course you need to pass, on average, each type of assessment (exam, prac reports, and assignments etc.). For example, if there are two tests you need to have an average of 50% to pass. But you also need to have passed the other assessments as well. You can’t make up marks from one type of assessment to another (eg pass the tests but fail the prac reports).

• Late work that is submitted without an application for an extension will not be corrected.

• Extension of time for submission of assessable work- A student may apply for an extension of up to 7 days from the original due date. They must lodge the application form (available on the web http://mams.rmit.edu.au/seca86tti4g4z.pdf ) at least the day before the due date. The application is lodged with the School Admin Office on Level 6, Bdg 51. Students requiring longer extensions must apply for Special Consideration (form available on the Web). For missed assessments such as exams- you (& your doctor if you are sick) must fill out a special consideration form. This form must be lodged at the HUB or online with supporting evidence (eg medical certificate), prior to, or within, 48 hours of the scheduled time of examination.

• In order to be successful in this module, you have to achieve a pass in all of the above assessment tasks. If you miss an assessment task due to unavoidable circumstances, you need to follow the procedure of special consideration and apply within the allowed time frame.
