Actuarial science is about 25% math, 25% statistics, and 50% financial economic theory/investment science. If you are an economics/math major this is something that you can consider for a career.
I am currently working as an actuarial analyst for one of the big 4, on the life and health side. I tend to find asset side work very interesting, and liability side work quite dry. Liability side work deals mainly with determining how much money insurance companies should set aside to pay for future claims. Asset side work includes providing investment strategies to clients, modeling investment products, creating hedging models, etc. I am planning to write the CFA exams along with my actuarial exams so I will be more involved on the asset side.
The exams are difficult, and very time consuming, but you get up to 150-180 hours of paid study time off from your company, and a raise of 3000-5000 for passing each exam, as well as a couple thousand dollar bonus for passing on first try, which is the rewarding part of being in the actuarial profession.
If the ideas of starting out with a good salary, getting 30-40 days of paid study time per year, getting raises and bonuses for passing exams (getting paid to study as opposed to paying a tuition to study) appeal to you, you can consider the actuarial profession.
