CPAExamsMastery.com is the editorial and learning layer for U.S. CPA exam preparation in the Mastery ecosystem. The site exists to explain the underlying concepts well enough that later question practice becomes faster, more accurate, and less dependent on guesswork.
The site is organized around stable U.S. exam roots at /aud/, /far/, /reg/, /bar/, /isc/, and /tcp/. Each root is meant to become a real guide home with chapter mapping, review support, and an appendix layer that can eventually include study plans, cheat sheets, resources, FAQs, and glossaries.
The existing numeric folder tree remains the structural fallback during routine improvement work. Coverage depth should improve without rewriting the public root architecture unless structural cleanup is explicitly requested.
CPAExamsMastery.com teaches first. When a reader wants timed drills, mixed review, or a separate practice interface, that intent should move to MasteryExamPrep.com rather than turning this domain into a product, billing, or support site.
That boundary keeps the CPA guide library focused on explanation quality and lets the practice platform own account, subscription, and app-specific workflows.
