Is the practice really free, or does it stop after a few questions?
All 400 questions, the timed mock and the report are free with no sign-up. A free account only adds saving your progress. The study guide book is sold separately, $14.99 one-time; nothing in the practice requires it.
Is your mock the same as the real CSLB Landscaping (C-27) Trade?
No. Ours is 100 questions in 210 minutes; the real exam is 210 minutes long. Use the mock for stamina and section timing, not as a score predictor.
What score do I need?
Not published by CSLB. CSLB: “You will be informed at the test site about the percentage of correct answers needed to pass each examination,” and, in Get Licensed to Build Q14, that the percentage “varies for each exam”. Passing candidates are never shown their own score. PrepPass states no passing score for this exam.
