The challenge

The Assessment of Clinical Judgement: 150 questions, a pass mark of 75 %, and a licence that depends on it.

The exam covers every field of dentistry, from endodontics to oral surgery and practice law. Textbooks do not tell you what NDEB actually asks.
150 questions in 330 minutes leave about 132 seconds per question. Speed has to be trained, not hoped for.
The question style is specific: clinical scenarios, best-answer choices and distractors that look right.
Working full time leaves little room to plan revision, and a retake costs months of waiting and another exam fee.

How MediFlow solves it

A question bank built on the published content of NDEB, organised by topic, so you know what matters.
Timed mock exams in the real exam format train your pace before the real day.
Every answer is explained, including why the other options are wrong.
A study plan up to your exam date tells you what to do each day and brings weak topics back for review.
