Common questions
Before you start.
Choosing C-27 exam prep: what should it include, and how do I avoid paying for the wrong material?
CSLB doesn't require a school, so prep is optional. If you buy it, check that it follows CSLB's six C-27 areas for exams from July 1, 2026, explains every answer and shows which areas you miss. Try before you pay: take the free 20-question C-27 test or open the full demo with a free account. Test2Pro is online practice only; you apply, schedule and test through CSLB and PSI.
Applying for your first license: do I need Law & Business too, and can I skip it?
Most first-time applicants must pass both C-27 and Law & Business. You skip Law & Business only if CSLB waives it for you. You can add it to your C-27 prep from the purchase card on this page.
Planning your study time: how long should I prepare, and how do I avoid running out of time?
There is no set time. CSLB gives you 18 months from the day it accepts your application to pass, and after a failed try you can retake the exam in 21 days for a new fee. Choose a longer term if several of the six areas are new to you, or a shorter one if you already work across most of them.
When your access ends: what happens, and will I be charged automatically?
Your access ends when the months you paid for are over. It is a one-time payment, not a subscription, so nothing is charged automatically.
What is AI Pro?
AI Pro is free for everyone. Get explanations, ask follow-up questions, and study in your language.
Studying between jobs: can I practice on my phone?
Yes. Practice works on phone, tablet and computer, and you pick up where you left off.
