Hi, in tutorial 9, subquestion 2, we chose to use object diagram to illustrate the following description. However, I am a little curious about how to show that the two assignments are optional in object diagram.

Use a normal object with isCompulsory = false?

Thank you very much Prof Damith! I think I have misunderstood it initially haha, I first thought that optional means that we need to consider different situations regarding the various completion states of the assignments. But I now got it, it refers to the attributes of the assignment itself.
