Why Clodia exists
Clodia is a UK-based platform building preparation for the exams that stand between international healthcare professionals and their registration, starting with the OET. Further healthcare exams will follow once their material meets the same standard.
We built it after watching the same pattern repeat across candidates: months of attempts scoring in the 310s, close enough to feel cruel, far enough to feel impossible, while the available apps offered the same thing: stock practice tests, generic feedback (“needs more practice”), and a price tag that makes every failed attempt feel expensive.
What actually moves candidates from 310 to 350 isn't more tests. It's knowing what specifically goes wrong: the exact pattern of incomplete noun phrases in Reading, the missing empathy cues in Speaking, the over-long letters in Writing, and drilling those, by name, until they're fixed.
That's why Clodia exists. Every feature exists because a real candidate failed a practice test, sat with vague feedback, and needed the app to say exactly what went wrong and exactly which five-minute drill would fix it.
What makes this different
Built for 310→350
Every micro-drill targets the specific gaps that keep candidates stuck below Grade B. Not generic OET practice.
Strict marking
Clodia's marking is built on the published OET assessment criteria and is genuinely unflattering. No inflated scores. It is practice marking, not an official OET result.
Built with candidates
Developed alongside people resitting the exam. Every feature traces back to a real failure pattern, not a marketing roadmap.
What this app is not
- Not affiliated with OET. Cambridge Boxhill Language Assessment runs the real OET. We're an independent preparation service.
- Not a guarantee. Your estimated OET score is a guide to where you stand, not a promise of your real result.
- Not for clinical use. Every practice case is fictional. Don't make patient-care decisions based on anything here.
- Not just for nurses. All 12 OET professions are covered. Reading and Listening are shared, as in the real exam; Writing and Speaking are written for each profession.
