80/20 Golden Rule · Pareto Optimality

The method

Evidence decides what gets taught

The 80/20 rule governs selection, never treatment. A concept that survives the cut is taught exhaustively; one that does not is cut whole. Broad, thin coverage is the thing we refuse to produce.

Stage 01

Mine the papers

Every past paper, assignment, memorandum and examiner's report is read before a single page is written.

Stage 02

Weight by frequency

Sub-concepts are tabulated by sitting and by marks. In RSK4805, two learning units carry 330 marks — nearly half the paper.

Stage 03

Select on the 80/20 rule

The high-yield fifth is treated exhaustively, the rest briefly. Nothing unnecessary is written.

Stage 04

Work it on one case

A single South African case business runs through every part, computed once and asserted across the set so figures never drift.

Stage 05

Prove it by machine

Nineteen automated checks per document — table integrity, render fidelity, figure carry, tone. A figure typed into prose fails the build.

Stage 1 — Mine the papers

Before a page is written, every held past paper, assignment, memorandum and examiner's report for the module is read. The object is not to collect questions but to find out what the examiner actually asks, and how often, across as many sittings as can be found.

Stage 2 — Weight by frequency

Each paper is broken into sub-concepts and tabulated by sitting and by marks. The result is a table that says, for this module, where the marks have been. In RSK4805 Market Risk Management, for example, two learning units carry 330 marks across the sittings held — nearly half of everything examined.

Stage 3 — Select on the 80/20 rule

The concepts that carry the marks are treated exhaustively: every formula with its symbol table, every technique with a worked example, every recurring trap named. The rest are treated briefly or not at all. The rule decides what is in; it never licenses thin treatment of what is in.

Stage 4 — Work it on one case

Wherever the module allows, a single South African case business runs through every part of the notes. Its figures are computed once and asserted across the whole set, so a number in part 7 agrees with the same number in part 2 — and a student learns one business deeply instead of twenty superficially.

Stage 5 — Prove it by machine

Every document passes nineteen automated checks before it ships: table integrity, render fidelity across Markdown, Word and PDF, figure carry from computation to prose, heading structure and tone. Figures are computed in code and inserted, never typed — a figure typed directly into prose fails the build.

When the memorandum is wrong

Official memoranda contradict their own question stems more often than students expect. When that happens, the contradiction is resolved by working the question from first principles, the decision is recorded in the document, and it is numbered so it can be cited. It is signed off by the author, by name.

The output

What the method produces

The notes

One part per learning unit, in six numbered sections: how it is examined, the conventions, the ground, the answer shapes, what loses the marks, and a self-test.

The packs

One pack per sitting, built to the structure that paper itself prints. A set question is never parted from the answer beneath it.

The revision reference

The module compressed to what survives the last fortnight, weighted by the same frequency evidence that built the notes.

The formula sheet

Every formula with a symbol table defining each term, and the technique for deploying it — indispensable where the venue supplies nothing.

On academic integrity

Our material is written to be studied from. Model answers exist so a student can see what a full-mark response looks like and learn to build one — they are not submission copy, and we do not write or submit assessments on a student's behalf. Every institution we serve requires original work, and so do we. This is the line that separates us from the assignment-writing services advertising alongside us, and we would rather lose the sale than cross it.
