How to use it

Getting the most out of the atlas

Five minutes of orientation, and two study routes depending on whether you have half an hour or a fortnight.

Three ways in

The term list
The default view. Sixty terms in five families, in the order a placement is built, each with a one-line summary. Click a family in the left rail to show that family on its own.
Search
Press / from anywhere to jump to the box. It matches names, aliases and definitions, so “xs”, “priority” and “deductible” all find the right layer terms.
Take me somewhere
Bottom of the left rail. Opens a term you have not marked as learned yet — useful for a five-minute session.

What each part of a term page is for

Every term follows the same structure, and the parts are meant to be done in order.

  1. Definition and key points. The formal meaning, then the two or three things practitioners actually argue about. Where a term has a formula, it sits at the end of this block.
  2. Worked example. One paragraph, one set of numbers, no narrative. This is the sentence to remember.
  3. Structure at a glance. On the terms where the shape of the deal is the lesson, a diagram: a tower showing the retention, each layer and where the programme runs out, or a set of bars showing how premium and losses divide. Read the figures beside the diagram, not the proportions — band heights are compressed so every layer stays legible.
  4. Scenario. A named company, a real situation, and a ledger of figures in US dollars that you can follow line by line. The closing “so what” line is the point of the whole page.
  5. Quiz. Two questions. Answer them before reading the explanations — the explanation is written for the mistake, not for the right answer.
  6. Word problem. Harder than the quiz and deliberately multi-step. Work it out on paper first; the hint is a nudge, and the worked answer shows every line.
The discipline that makes it work

Do not open the worked answer until you have written a number down. Recognising a correct solution feels identical to having produced one, and only one of those survives into a renewal meeting.

A 30-minute tour

If you only have one sitting, these six terms give you enough to follow most placement conversations:

  1. Reinsurance — why the transfer exists at all.
  2. Retention & Cession — the one distinction everything else rests on.
  3. Quota Share — proportional thinking in its simplest form.
  4. Excess of Loss — non-proportional thinking, and why it is different in kind.
  5. Reinsurance Tower — how the two combine into a programme.
  6. Rate on Line & Payback — the shorthand the market prices in.

The full syllabus

Work down the term list in order, two sessions per family — the first six terms, then the next six. Ten sessions of about an hour each covers everything. Mark each term as learned when you can do its word problem without the hint — the progress ring in the toolbar and the bars in the left rail track how far you have got.

Before an exam, come back through the formula reference. If you can state what each formula is for and where it bites, you know the material; if you can only recite it, you do not.

Keyboard and printing

/
Jump to search from anywhere on the atlas page.
↑ ↓ ⏎
Move through search results and open the highlighted one.
Esc
Clear the search box, or return from a term to the list.
Print this term
On any term page. Printing expands the hints, worked answers and quiz explanations, and keeps the structure diagram, so the printout is a complete handout — useful for classroom sessions.

Your progress, and where it lives

Learned marks, quiz answers, your theme and your cookie choice are stored in your own browser and never sent anywhere. That has two consequences worth knowing: your progress does not follow you to another device or another browser, and clearing your browsing data clears it. “Reset my progress” in the left rail wipes it deliberately.
