Everything you get — in full
Differential-reasoning practice for exam preparation — decision support for study, not a diagnostic device. Every material, every format, and a preview of the content — so you know exactly what you’re getting.
Built for focused practice
Fast when you are drilling. Rigorous when you have more time. Works on phone, tablet, and desktop without friction.
Criteria-in-Context is optimised for phone use on the go — fast lookup, cardinal features first, no scrolling walls of text.
Every material exports as a clean, branded PDF — keep it alongside your session notes or print for supervision.
A-vs-B resolution grids surface the distinguishing feature at a glance — without opening the manual.
Applied case reasoning walks through overlapping presentations and lands on a defensible diagnostic statement.
A media layer, in production
Every reference is a fully interactive online page and a branded PDF today. A visual and audio layer is being produced for point-of-care use — included as it’s released.
Reveal-on-click decision grids, fast-lookup criteria, and worked vignette trees.
Decision diagrams and discriminator maps as standalone visual aids.
Narrated point-of-care reasoning for between-session review.
Short videos walking the vignette decision trees to a defensible statement.
The full index — all 6 materials
All materials are authored and reviewed before release.
Framework · 1
How to use this set to practise differential reasoning — and how Differential Reasoning differs from Mastery. The fast routine for reaching a defensible formulation under exam conditions.
Criteria · 1
Fast-lookup criteria with clinical traps surfaced — cardinal features first, threshold and duration cues, built for one-handed mobile use while you practise.
Differentials · 1
A-vs-B decision rules for overlapping presentations — rehearse the distinguishing features at speed without scrolling pages.
Specifiers · 1
When each specifier applies, how it shapes the formulation, and what to document. Specifiers are routinely missed in busy practice.
Case reasoning · 1
Applied case reasoning when criteria sets overlap — reads like a clinical scenario, walks the differential, surfaces the decision rule, lands on a defensible diagnostic statement.
Compliant use · 1
Educational-use-only framing — refers explicitly to the official APA DSM-5-TR as authoritative; supervision-aware language; not a diagnostic device.
