ADC Written Exam Format — Structure, Scoring & What to Expect
Everything you need to know about the Australian Dental Council Written Examination before you start preparing. The format, the structure, the question style, and the details that most guides skip.
The basic structure
The ADC Written Exam is a computer-delivered, multiple-choice examination held over two consecutive days. It is conducted at Pearson VUE test centres worldwide, usually twice a year — in March and September.
The exam consists of 280 questions divided into 4 papers, with each paper containing 70 questions and a 2-hour time limit. Day one covers Papers 1 and 2, day two covers Papers 3 and 4. You must sit all four papers in a single examination session — you cannot split them across different sittings.
The clinical vignette format
This is the part most candidates underestimate. ADC questions are not standalone MCQs. They use a clinical vignette format — an overarching patient scenario followed by 5 related questions.
A typical vignette presents a patient walking into your clinic. You get their age, medical history, presenting complaint, examination findings, and sometimes radiographs. Then you answer 5 questions about that same patient — diagnosis, investigation, treatment planning, pharmacology, and follow-up. The questions are linked; understanding the vignette correctly is the foundation for all 5 answers.
With 280 questions across 4 papers, you're working through 56 clinical scenarios over 2 days. That's 14 patients per paper. The exam tests clinical reasoning and decision-making, not rote memorisation.
What domains does it cover?
The ADC Written Exam assesses competencies across four broad domains: health promotion and disease prevention, patient assessment and diagnosis, treatment planning and management, and critical thinking and evidence-based practice.
Within these domains, questions span 13 clinical disciplines — everything from oral pathology and pharmacology to radiology, dental materials, periodontology, endodontics, prosthodontics, oral surgery, paediatric dentistry, orthodontics, and more. The exam expects you to think like an entry-level dentist practising in Australia, applying Australian clinical standards and guidelines.
The scoring
Each correct answer scores equally. There is no negative marking — you are not penalised for guessing, so you should always answer every question. Your final score is based solely on the number of correct answers.
Results are released approximately 6 weeks after the exam date through your ADC Connect profile. A pass is valid for 3 years, within which you must complete the Practical Examination. There are no limits on the number of attempts.
What makes it hard
The ADC Written Exam is not testing whether you know dentistry — you're already a qualified dentist. It's testing whether you can apply your knowledge in the Australian clinical context. That means knowing the Therapeutic Guidelines, understanding Australian prescribing conventions, and making clinical decisions that align with Australian standards of practice.
The vignette format adds another layer. You can't memorise your way through scenario-based questions. You need to read the case, identify the key clinical features, and reason through each question within the context of that patient. Speed matters too — roughly 1 minute 42 seconds per question, which leaves no room for overthinking.

Read the prescribed textbooks — especially the Therapeutic Guidelines, which is the single most tested resource. Build your study plan around the 4 domains and 13 disciplines, but don't study them in isolation. The exam tests integrated clinical thinking, so your preparation should mirror that.
Practise with scenario-based questions from the start. Isolated MCQs build knowledge, but vignette-based practice builds the clinical reasoning muscle you actually need on exam day. Track which disciplines and topics you're weak in, and allocate your time accordingly.
Time yourself. If you can't answer 70 questions in 2 hours consistently, exam-day pressure will make it worse. Build the habit of reading vignettes quickly, extracting key information, and committing to answers without second-guessing.
