The challenge

The NZ Dentist Registration Examination (NZDREX) decides whether DCNZ grants your licence.

The exam covers every field of dentistry, from endodontics to oral surgery and practice law. Textbooks do not tell you what DCNZ actually asks.
Time pressure in the exam is real, and pacing has to be trained in advance.
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.
The oral or practical part is hard to practise alone.

How MediFlow solves it

A question bank built on the published content of DCNZ, 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.
An AI examiner lets you rehearse the oral or practical part at any time.
