Practice 1
This is a practice of the upcoming alternative assessment task
(Term 1 Week 7).
We are going to do this Practice as Homework so that you have an idea how the
assessment is going be like, and at the same time to iron out any potential technical
issues.
Based on feedback from your seniors, this practice is going to
be very helpful in preparing you for the alternative assessment.
The submission date for the practice Viva Voce is Friday 7 Feb
2359 hours.
The task is compulsory, and you are to submit your work via the platform
instructed by your teacher.
