Once you’ve decided to study science, the next step is to choose a major, and the good news is there are a lot to choose from!
So you’ve decided to study science at uni — nice one!
Now to the hectic task of choosing which major – there are literally dozens on offer. Use this quiz to help narrow down your science study options based on your interests.

You can find more detail on many science study majors, along with course options in our latest undergraduate course guide, developed in partnership with Macquarie University.
It features Macquarie University graduates Steph Bagala and Sean Diprose on the cover. Steph chose marine science and Sean chose statistics, showing just how diverse science study can be!
And here’s a taster of the majors offered at Macquarie University, and what they involve.
