For doctors in training and medical students
A diagnostic learning coach for the one skill nobody marks you on.
You are examined constantly on knowledge and almost never on diagnostic reasoning itself. This is a diagnostic learning coach that sits you down with a case, asks for a differential with a likelihood for each diagnosis and a piece of diagnostic reasoning, marks it privately, then questions you toward your single biggest reasoning gap — without saying whether you are right or wrong, and without handing you the diagnosis.
US$3.00 per top-up. Provided at cost — see below.
How a session runs
Work a real case
A case is drawn from the library and re-cast before you see it, so one you have met before will not read the same way twice. Every clinical value is preserved exactly. Or bring your own case.
Commit a differential
Name each diagnosis and choose a likelihood: working diagnosis, less likely but needs considering, or unlikely but needs excluding. Then write the diagnostic reasoning that holds the list together.
Be questioned, not told
Your list is marked privately against an independent review. The diagnostic learning coach then asks two rounds of questions toward the highest-yield gap, reflecting your patient's findings back — never saying whether you are right or wrong, and never handing you the diagnosis.
Take feedback when you are ready
After your first reply you can submit your answer at any time, or keep going through the two standard questions and any extras you opt into. If something important is still missing when you are offered the choice to continue or take feedback, that choice suggests speaking with your senior doctor, and repeats it if you keep going. The mark, diagnostic learning coach's note, reference differential and scoring are revealed together.
What you are marked on
Five components, shown to you in full
The mark is arithmetic, not an impression. The clinical judgements come from a deep review of the case; the score is then computed from those judgements the same way every time, and every component is broken out so you can see exactly where the marks went.
- Leading diagnosis (40)
- Your first working diagnosis, or at least 25 if you named it as a later working diagnosis.
- Coverage of likely diagnoses (30)
- An equal share for each diagnosis the diagnostic learning coach treated as most likely (posterior > 20%).
- Unlikely but needs excluding (20)
- Whether the catastrophic diagnoses made your working-diagnosis or needs-excluding list.
- Diagnostic reasoning (5)
- Whether your write-up uses specific findings from this case to justify the list and each likelihood.
- Likelihood assignment (5)
- A focused working-diagnosis list, correct likelihoods, specificity and restraint.

Pricing
US$3.00 a top-up, at cost
Each session commissions a genuinely deep piece of clinical reasoning, which costs real money to run. What you pay covers that reasoning and the hosting that delivers it. There is no margin on top and no cheaper way to provide analysis of this depth. A usage meter shows you exactly how much of your current top-up you have used.
