How to study with the reference library

Overall, the library works best when it supports practice, not when it replaces it.

If studying FPC:Start with terms, forms, basic tax concepts, and payroll calculation vocabulary.
When studying CPP:Go deeper into controls, deposits, adjustments, compliance scenarios, and operational judgment.
Covering weak areas:Read one reference page, then answer related questions while the concept is fresh.
Checking current figures:Use official source links before memorizing year-specific thresholds or rates.
