Actuarial Science(精算), Risk Management (風險管理)

In HKU, they are just the same thing. For major they call it actuarial science, and if you choose to minor it, another title, minor in risk management is offered.
However, actuarial science graduates generally work in insurance company, to calculate those loss model, and the courses of actuarial science is more difficult. And student got a minor in risk management usually are students studying economics, business or finance, so normally they'll work in the finance field.

.........totally rubbish answer.
plz discuss it from a academic sense but not a program sense.
