so if I did maths as a single degree at uni, how broad would my job prospects be?I study the maths/eco combination. If you're really into maths and economics as areas of study per se, then do the maths and economics combination. If you want to become an actuary, do actuarial studies. The maths and economics combo is much more flexible in terms of career options, but unlike actuarial studies, there isn't a straightforward/obvious career path for you to walk into.
That depends on your major. Doing a 3-year advanced mathematics degree means you can have up to two majors. And even your compulsory mathematics major can be pure/applied mathematics (at USYD, we don't distinguish between undergraduate pure/appled maths majors), financial mathematics or mathematical statistics. Your second major can also be one of the above, or something else from science (computer science is a popular second major for maths students).so if I did maths as a single degree at uni, how broad would my job prospects be?
