    2. The 2024 A levels score is based on four Advanced Level (A2) subjects. Entry scores are calculated from the best three or four A2 subjects (excluding repeated subjects) using the following values: A*=6, A=5, B=4, C=3, D=2, E=1. At most one Applied A Level subject may be included in the best four subjects used to calculate the aggregate.

The era of Big Data

With quintillion bytes of data generated every day, we’re in the era of big data. Social media, the Internet of Things (IoT), machine learning, and artificial intelligence are driving trends in data and influencing the role of data scientists. The increasing need for people who can interpret and understand data means that data scientists and analysts are in very high demand across a range of industries.

What does a career in this field look like?

Data science is a multidisciplinary field of study that blends mathematical methods, statistics, computing, business decisions and communication. Data scientists translate user data into insights that help companies understand their audience and personalise their products or services. Uncovering new insights and predicting trends has become vital in the retail, environmental, not-for-profit, IT, and professional services sectors.

Career opportunities in data science span many industries, from start-ups to established corporations, including Coles, AirBnB, Spotify, Netflix, and Greenpeace, to name a few. As a data scientist, you might be asked to calculate the price of new products for the market, determine warehouse or retail employee schedules, make predictions of environmental phenomena and model the spread of new diseases.

Our alumni

"My favourite part about the Data Science and Decisions degree was that I could customise it to fit my interests. I got to pick electives from a pool that contains everything from software construction to calculus to economic game theory. This allowed me to follow my passion for mathematics while also building on my newly discovered love of coding, and then get to throw a bit of economics into the mix!"

Jessica Boyle

Consultant, Data Assurance, PwC 

"The data science program at UNSW has provided me with a solid foundation in advanced mathematics and computer science, as well as the opportunity to pursue elective courses in physics. Knowledge of these three fields has proven invaluable to my career as they are fundamental to almost every industry."

Saksham Yadav
