Why a practice test is the fastest way to find out where you stand
The single biggest waste of time in contractor exam prep is studying the wrong material. Most candidates can recite trade trivia they already know — and lose the exam on business law, math, and safety topics they thought they'd "just pick up." A practice test reveals the gap in 15 minutes.
Our free Contractor Readiness Test asks 25 questions sampled across all major content areas of the California General B exam. When you finish, you see:
- Your overall score (% correct)
- Your Pass Probability™ — the model's estimate of your likelihood of passing the real exam today
- A breakdown by category: business law, contracts, estimating, safety, planning, and trade knowledge
- The specific weak areas to focus on next
How our practice questions are written
Every question is hand-written by California-licensed instructors and reviewed against the CSLB exam blueprint. We don't use leaked or scraped exam questions — those are confidential and using them violates CSLB policy. Instead, we write new questions that test the same concepts at the same depth, with the same multiple-choice format and similar distractor patterns.
Premium subscribers get access to the full classification-specific practice bank (in active development) and unlimited timed mock exams. See pricing.
How to use a practice test effectively
One practice test in isolation tells you very little. Used as part of a system, it tells you everything:
- Take a baseline test cold. No studying first. Whatever score you get is your starting point.
- Study the weak areas the test surfaces. Don't review the topics you already know.
- Take a fresh practice test every 1-2 weeks. Watch your Pass Probability climb.
- Take 3-5 full-length timed mock exams in the final 2 weeks before your real exam.
