How to study for it
- Study in proportion to the weights. The DANB® exam-preparation page advises starting from the exam outline and its percentages; here Procedures alone is 39 % of the exam.
- Keep one textbook from the outline’s reference list. The CP exam outline lists the textbooks and reference materials used to develop the exam, and the same page suggests having at least one recommended dental assisting textbook.
- Practise against the clock. 80 questions in 60 minutes leaves about 45 seconds a question.
- Give it time. According to the same page, many test-takers say they studied for at least one to two months, and it suggests setting aside a few hours each week; it also offers a demo exam to show the screens beforehand.
