The REG (Regulation) section of the CPA exam tests your knowledge on business law, business ethics, and federal taxation. It will have some significant changes starting in April of 2017. The REG exam is increasing the multiple choice questions from 72 to 76 and weighting them at 50% instead of 60%.
The remaining 50% comes from 8-9 Task-Based Simulations instead of 6, otherwise known as the SIMS, which require you to generate answers on your own rather than choose from a list of possible choices. You are now given 4 hours to complete the exam, instead of 3 but still need to get an overall score of 75% or higher to pass.
Ethics & Professional and Legal Responsibilities
Federal Taxation on Entities
Federal Taxation on Individuals
Federal Taxation on Property
