Learn the skills. Keep your money.
Short, genuinely useful lessons in the three things that compound fastest: the Excel that gets offers, the methods that fill your first job, and the money habits that make the exam years lighter. All free, forever.
Excel for actuaries (3)
The formulas interviewers test: XLOOKUP, INDEX-MATCH, dynamic arrays. Taught on actuarial problems.
XLOOKUP vs INDEX-MATCH: which one, when, and why
The two lookup workhorses of actuarial Excel, full syntax, the exact situations each wins, and the interview trap of only knowing VLOOKUP.
Start the lesson →Dynamic arrays: FILTER, UNIQUE, SEQUENCE & SUMPRODUCT
The four array functions that replace half your manual work: filtering claim lists, deduplicating policies, generating schedules, and conditional math without helper columns.
Start the lesson →Mini-project: build your own exam study dashboard
A 30-minute build that practices XLOOKUP, SEQUENCE, and conditional formatting while producing something you'll actually use every day until your sitting.
Start the lesson →Technical methods (3)
Chain ladder, Bornhuetter-Ferguson, and the reserving toolkit, with real triangles and real numbers.
Chain ladder from scratch: your first loss triangle
The reserving method every analyst meets in month one. Built with actual numbers, from raw triangle to IBNR, including the judgment calls the textbook skips.
Start the lesson →Bornhuetter-Ferguson: the intuition, then the formula
Why the most-cited reserving method is really a credibility blend, with the same numbers from the chain ladder lesson, so you can feel exactly what changes.
Start the lesson →The reserving methods map: ELR, chain ladder, BF, Cape Cod
Four methods, one decision framework. What each assumes, when each wins, and how real reserving actuaries actually blend them across a triangle.
Start the lesson →Actuary explains money (1)
Personal finance built for the candidate life: the raise ladder, the sinking fund, the first-paycheck plan.
