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 task is COMPULSORY, and you are to submit your work via the GoogleForm at the end of this page.
