Assessment

Edit Assessments Content

Details on the course assessment – including due dates – are provided in the introductory sections of both the laboratory manual and study guide. This includes instructions regarding length, structure, presentation, and style, and referencing format for the essay assignment. The dates indicated for assessment procedures will normally be adhered to. Any changes in the dates will be made in consultation with the class, at least one week prior to the original date.

Course work: final assessment ratio is 50:50.

Internal assessment (50% of final mark): one test on lecture content, worth 10%; Lectorails will also be assessed through four assignments.

Test will be conducted during the during the tutorial hour on Thursday the 16th Sept. The assignments will be equally weighted and make up 20% of the course grade.

Labs (including design and development project components) make up 20% of the course grade. At least 70% of labs must be handed in for marking.

External assessment: final assessment (50%) will be a supervised event held during the examination period of the semester. This will be one to three hour event. Format will be informed later, based on the current Covid-19 related guidelines from the university management. A minimum mark of 40% is required in the final assessment in order to receive a passing grade.

This paper facilitates the development of technical writing, an important competency expected of a scientist and engineer. In order to pass this paper, students are expected to demonstrate their ability to produce written work of an adequate standard.
