How Many Questions Should You Do Before a Dental Board Exam?

Why there is no magic number

Candidates often hear figures such as "do 3,000 questions" or "finish two question banks". These numbers are easy to count, which is why they spread. But two candidates can answer the same number of questions and learn very different amounts. One answers quickly, checks the score and moves on. The other reviews every option, flags every guess and returns to weak topics until they hold. The second candidate learns far more per question.

No examining body publishes a recommended number of practice questions, and none of the AFK, INBDE, ORE or ADC tests whether you have seen a particular question before. They test whether you understand concepts well enough to recognise them in a new form. So the useful question is not "how many?" but "how much of the blueprint have I covered, and how reliably?"

What to measure instead

1. Coverage

List the topics your exam can test. DentistUP, for example, divides dentistry into 29 branches and 263 topics. Coverage is the share of those topics you have practised at least once. Gaps in coverage are the most expensive, because an untouched topic produces guesses on exam day.

2. Depth

For each covered topic, have you answered questions on it in several different forms, and can you get a fresh question right? One set of ten questions shows whether you know a topic today. A second set a week later shows whether you remember it.

3. Confidence

Track guesses separately from errors. A correct guess inflates your score and hides a gap. Many candidates find that marking uncertainty changes their picture of their own readiness more than any other habit.

4. Review debt

Keep a list of every question you got wrong or guessed. If the list grows faster than you clear it, you are doing too many new questions and too little review.

Realistic targets

With those measures in place, numbers become useful as planning tools rather than goals. As a guide:

• Daily: 20 to 60 new questions with full review, alongside lesson study. At the lower end if you are working full time, at the higher end in the final weeks.
• Weekly: one mixed set across all topics covered so far, and two or three sessions spent only on your review list.
• Per topic: at least three focused sets of around ten questions, spaced out, before you consider a topic secure.
• Full mocks: several in the last six to eight weeks, each followed by targeted topic work before the next.

Put together, a candidate who studies for six months at this pace will answer several thousand questions. That is a result of good coverage and review, not the target itself.

How to review a question properly

Reviewing takes longer than answering, and it is where the learning happens. For each question:

• Say why the correct answer is correct, in one sentence.
• Say why each wrong option is wrong, or what it would be the answer to.
• Name the concept being tested.
• If you guessed or were wrong, add it to your review list and return to it after a few days.

If that sounds slow, it is meant to be. A carefully reviewed set of 20 questions usually teaches more than 100 answered at speed. Our guide on why passive review fails explains why retrieval and review work better than rereading.

When more questions stop helping

There are clear signs that adding more new questions is no longer the best use of time:

• Your mock scores are flat despite more practice. This usually means the same weak topics keep failing and need lesson time, not more questions.
• You recognise many questions from memory. Switch to a fresh source or to topics you have practised least.
• Your review list keeps growing. Pause new questions for a few days and clear it.
• You are tired and accuracy drops late in the day. Fewer, better-reviewed questions will serve you better.

Mock exams: how many and when

Full mock exams measure readiness and build stamina, but they teach less per hour than topic-level practice because each covers many topics thinly. Start them once most topics have been covered, usually in the last six to eight weeks. After each one, group your wrong answers by topic and spend the following days on those topics before the next mock. A trend across several mocks is far more reliable than any single score.

Signs you are ready

• Every blueprint topic has been practised several times.
• Your recent mock scores are stable and comfortably above the level you are aiming for.
• Few questions still feel like guesses.
• Your review list is shrinking.

None of these guarantees a result, but together they are a much better signal than any question count.

Start with a baseline

If you do not know where you stand, take a free 100-question practice exam for your pathway: AFK, INBDE, ORE or ADC. Then use the free practice questions by branch to check your weakest areas one at a time.
