Entry requirements
-
- The 2024 Lowest Selection Rank (LSR) is the adjusted rank (ATAR plus adjustment factors) you would have needed to gain entry to this degree in 2024.
- 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 2024 IB Diploma is an indication of the IB you would have needed to gain entry to this degree in 2024. It is to be used as a guide only.
- The 2024 Lowest ATAR is the lowest ATAR (before adjustment factors were applied) to which an offer was made. Where <5 is listed, this indicates that less than 5 ATAR-based offers were made and so the score has not been published. N/A indicates no offers were made on the basis of ATAR.

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听
"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."
