This unit is pretty interesting as you learn so much about marine organisms. There are 3 assignments which are all relatively straightforward. It also had an excursion where you do fieldwork at the beach and snorkel. The negatives of this unit are that it is very content heavy and you have to keep up with it for the fortnightly quizzes. The exam itself was pretty hard due to the fact that there is so much content you need to pick what to study as you likely won't get time to study it all in-depth. The exam is also a practical exam in the lab where you are asked to identify various organisms and explain certain life processes for plants
