If your exam strategy is to study longer and test later in the exam period, then plan for regional weather or unforeseen events like sudden need to change venue (power outages, COVID closures, staffing...) or other last minute issues impacting test centers.
The ABCP has one exam period per year that closes with all test centers on Aug. 31.
Exam Questions and Strategies
1. We have provided a small sample of questions used in past exams. Current exam questions, have only ONE correct response for each question. Current exams DO NOT have responses like the ones seen in these examples. Responses like "None of the Above", "All of the Above", or multiple options like "Both A & D" have been eliminated.
2. Exam questions have clues about other items that may be asked. For more practice questions, ask: "If the question is worded differently, which of the response selections would meet that new criteria?" For example: Sample quest. 1 answer options include: Bonferroni Correction...Tukey's A Test...Tukey's B Test...Mantel-Hanenszel Test...Fisher-Behren's Test. Are any of these nonsense options or are they other "tests" you should be able to differentiate, describe and define because the other "tests" [answers] may be correct for other exam questions? Build the questions that would make other possible choices a correct response to expand practice base.
3. ANSWER all the questions on the exam. Do not leave any responses blank! We have absolutely no penalty or loss of points for wrong responses. A guess that might be right is better than no option selected guaranteeing no credit for the question. Your score is based on (# correct)/(total questions on the exam).
