REG exam structure for testlets, time allocation, scoring, and pacing decisions.
This lesson explains how REG is delivered and scored so you can plan pacing around multiple-choice and simulation work. Focus on testlet structure, time pressure, and why balanced preparation matters more than chasing one question type.
REG is one of the three four-hour Core sections of the CPA Exam. It combines federal taxation, ethics, procedure, and business law in a format that requires both fast recall and multi-step application.
According to the AICPA blueprints effective January 1, 2026, REG contains five testlets:

A["Testlet 1: 36 MCQs"] --> B["Testlet 2: 36 MCQs"]
B --> C["Testlet 3: 2 TBSs"]
C --> D["Testlet 4: 3 TBSs"]
D --> E["Testlet 5: 3 TBSs"]
You can move freely within a testlet before submission, but once a testlet is submitted you cannot return to it. NASBA candidate guidance says candidates are offered a standardized 15-minute break after the first task-based simulation testlet, approximately midway through the section. That break does not count against testing time. Optional breaks after submitted testlets do count against the four-hour clock.
A practical pacing plan is to protect enough time for the last three testlets instead of overspending on the first two. Many candidates aim to finish the MCQ portion with substantial time left for simulations, then adjust within the TBS portion based on complexity.
MCQs in the REG section primarily evaluate knowledge and comprehension across key tax and regulatory topics, including individual tax, entity tax, ethics and professional responsibilities, and various business law areas. Each MCQ contains four potential answers, with only one correct answer.
MCQs make up half of the section score. Because each MCQ testlet must be submitted before you can move on, consistent accuracy and pacing matter more than trying to infer anything from question difficulty while you are testing.
Task-Based Simulations test not only your understanding of the content but also your ability to apply it to moderately complex and sometimes real-world scenarios. Whereas MCQs tend to be narrower in scope, TBSs often require several steps of analysis and application:
Because TBSs demand deeper engagement with the concepts, they are a key measure of higher-order skills (application, analysis, and, in some cases, evaluation). For instance, you may need to consolidate financial data spanning multiple taxes (federal income, payroll, excise) to identify compliance breaches or errors.
The REG section currently allocates 50% of the score to MCQs and 50% to TBSs.
From a strategic perspective, you should approach each type of question with an understanding that TBSs often require more time per question but carry half of your total exam weight. Given this balanced weighting, neglecting either MCQs or TBSs can significantly harm your score. Successful candidates usually excel by diversifying study efforts:
The AICPA uses a scaled scoring mechanism for the Uniform CPA Examination. A raw score is initially calculated based on the correctness of responses, then converted to the familiar CPA score scale from 0 to 99. The passing threshold is 75, which does not necessarily translate to 75% correct. Rather, 75 is a passing index on the scaled scoring system.
Key points about scoring:
Pretest items are included in both MCQs and TBSs to refine future exam iterations. The REG exam typically contains a small number of undisclosed pretest questions, which the AICPA uses to evaluate question reliability and difficulty before these items become scored in subsequent exam versions. You will not know which questions are pretest vs. scored. For that reason, approach every question seriously:
Suppose you are nearing the final hour of your exam and still have all three TBS testlets remaining. Each TBS testlet may contain multiple tasks within it. Whether it is a research question, filling out relevant lines on a tax form, or evaluating a court case scenario related to a partnership dispute, the complexity can vary significantly.
While navigating the testlets, you will have access to on-screen tools:
Familiarize yourself with these tools in advance. Many CPA review courses offer simulated exam environments to help you practice. Comfort with the software and interface can save valuable time, especially during TBSs, and reduce exam-day stress.
The mind frame you bring into the exam can significantly influence your ability to handle pressure and complexity. A few tips:
If you have a strong study plan aligned with the official Blueprints and integrate consistent practice of both MCQs and TBSs, you will be well-positioned to manage the demands of the REG exam. Understanding how your performance translates to a final scaled score—and prioritizing both the multiple-choice and simulation aspects equally—fosters the well-rounded exam strategy that tends to deliver passing results.
