Like most subjects in this degree, topics are covered at a high level. What you get out of this subject is what you put in. The assignments are not as difficult as later units, and you need to be aware of this if you complete this unit earlier than others. In my case, I did it in my last semester. While you should always follow the rubric I found grading of assignments for this unit were a lot more subjective and determined on the opinion of the marker, the rubric was too open to interpretation and personal opinion.
