When you choose mathematics
At the end of first year, during Intent to Register in March.
What to watch for
Mathematics, Applied Mathematics and Mathematical and Statistical Sciences are Science modules. Western's example on its OUAC-codes page: Math and Physics share code ES, so you add Science only once — 'Don't apply to the same code more than once.'
The same application also gets you to
Science is the entry point for 7 other majors at Western. You are not choosing between these at application time.
