What the official study guide covers, chapter by chapter, and how to turn it into a passing score.
The DOJ's FSC Study Guide is the source material for every question on the real test, and for every question in this app. Read the official PDF directly from the California DOJ: FSC Study Guide (PDF, oag.ca.gov). It's organized into six chapters — know these, and you know the shape of the exam:
Every question in this app's bank — 184 in total — includes an explanation and a page reference back to the study guide chapter it came from. When you miss one, you're not just told the right answer; you're pointed straight back to the source material so you can actually close the gap.
Mock exams here mirror the real thing: 30 questions, stratified across all six chapters, scored against the real 75% passing threshold. Choices are shuffled per attempt, so you're recalling the concept, not the letter. See the What Is the FSC? page for how this test fits into actually buying a firearm, or the FAQ for quick answers.
