It's an interdisciplinary field. You're required to study Mathematics, Statistics, Economics, and Finance. Even a bit of Accounting. It's like there's overlap... you don't do everything a Maths or Economics student does.
Traditional applications are insurance (general, life, health), pensions, and investment. But qualified actuaries and those who have studied actuarial science sometimes venture beyond these fields into enterprise risk management, banking, statistics, and really any area where these skills may be used (casinos, airlines, energy suppliers) or where risk and statistics are involved. At the very least, they can work in Finance, but may have to explain their degree.
It's not uncommon for those in the field to possess a Master's degree (could be a requirement in Australia - and such degrees are available in the UK) but it's not always necessary. At the same time, there is no requirement for any degree, Bachelor's or Master's, in Actuarial Science unless you are qualifying in Australia (it's complicated, because they require some graduate education even if you're not awarded a Master's degree).
It's not unusual for Engineers to move into Actuarial Science, given their Mathematical ability. Economics and Finance can be difficult, but they are no match for Mathematics.
If in America, Malaysia, and the UK, you need to pass external exams (for which exemptions via a degree exist), so it doesn't depend on what degree you choose. It's good that you're interested in Engineering, and there's always Mathematics. Some people with Statistics or Economics degrees qualify, others may have more exotic ones.
That's a lot to take in and you haven't started your A Levels yet. You need Maths. For Engineering you want Physics and Chemistry, and Further Maths helps in both. The only required subject is Maths but the Engineering combo will boost any application.
i am really quite good and interested in maths, accounts and physics, but kinda weak and uninterested in chemistry and biology, however i always manage to get an A for biology and chemistry too, kinda concerned about what should i further my studies in, thought of engineering or actuarial science.
However, i don't think i know really that much about them and am open to any suggestions about what other paths can i take, i feel like engineering is the only thing everyone i know that is into physics takes, what suggestions do u have for me?
