For the first four terms the Mathematics and Statistics course is identical to the Oxford Mathematics course, up to and including the compulsory core of the second year of the Mathematics course.
In the remainder of the second year, Mathematics and Statistics students have a choice of topics in probability and statistics. The third and (optional) fourth year has no compulsory courses and a wide range of options available from both Mathematics and Statistics.
You can choose to graduate after three years with a BA, or to continue to a fourth year to graduate with MMath. The fourth year includes a dissertation in a topic with a large statistical component. You don’t have to make the decision about BA or MMath until you are in your third year, and progression depends on academic performance.
