Two more kinds of hands-on work appear throughout Acttuary courses. Both run right here in the page, with nothing to install.
Worked calculations
You'll be asked to compute things and check your own answer. The grader allows sensible rounding.
Here's one. An insurer expects 1 claim in every 200 policies each year, and each claim costs an average of £8,000:
Work it out
An insurer expects 1 claim in every 200 policies a year, and the average claim costs £8,000. What is its expected annual claim cost for a single policy, the risk premium?
That one-line calculation (frequency × severity) is where most general insurance pricing starts. The risk premium is also called the expected loss cost.
Python in the browser
Actuarial teams increasingly work in Python. Press Run below. The code executes in your browser (the first run takes a few seconds while Python loads):
Edit the numbers and run it again. What happens to the premium if claims double in size?
What's next
The third lesson in this sample sits behind the paywall, so you can see exactly how that works before you subscribe. It carries the fourth kind of exercise: a spreadsheet that runs this same frequency × severity across three rating cells and marks the formulas you build, not just the totals they produce.
