About this app & study resources
Hard Hat Qualified is an independent practice app for California contractors. Practice includes business calculations. The bank includes 150 repeat entries for reinforcement across tests. Each question appears at most once in any test. It is not affiliated with CSLB, and practice scores do not predict passing. Timed quizzes use an app-specific allowance of 90 seconds per question.
Your missed-question list is saved in this browser on this device. No account is needed. Clearing site data removes your saved progress, and progress does not sync between devices. Previous ChatGPT account progress is not transferred. Each question stays on the list until you answer it correctly in a practice session or timed quiz. Current answers and scores last until you close or refresh this page.
