Three steps

The Diagnostic Journey

01

Answer the questions

Choose timed or untimed mode. Flag questions, navigate freely, and your progress autosaves in this browser.

02

See evidence-based readiness

A domain evidence matrix, confidence calibration and a transparent review ranking — never a pseudo-scientific composite score.

03

Review every explanation

Ten structured teaching sections per question, plus official references, only revealed after you submit.

What this diagnostic is — and is not

Transparent by Design

  • Scoring uses exact-set matching with no partial credit; unanswered questions are never counted against you — accuracy is correct ÷ attempted, never correct ÷ the full question count.
  • Domains with fewer than three questions are always labelled "Limited evidence" and can never cause a downgrade.
  • Progress, answers and confidence never leave your browser — nothing is transmitted anywhere.
  • This is not an official exam, an accredited course, or a pass-rate guarantee.
