The challenge
The National Board Dental Hygiene Examination: 350 questions, a pass mark of 75 %, and a licence that depends on it.
- The exam covers the theory and the practical standards of your profession. Textbooks do not tell you what JCNDE actually asks.
- 350 questions in 450 minutes leave about 77 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 JCNDE, 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.
