CSLB Law and Business practice exam

115 questions · 3½ hours · four choices each

115 four-choice questions on the real 3½-hour clock, drawn from every section of CSLB’s study guide in proportion to its weight (15 organization and licensing, 17 business finances, 23 employment, 14 insurance and liens, 24 contracts, 6 public works, 16 safety). One question on screen at a time with the time remaining at the top, as at PSI. You get a score for every section and a review of every question with its explanation.

Before you start

Every question has four choices and one BEST answer, as on the real exam. Each explanation says why the answer is right, why the most tempting wrong answer is wrong, and which law or code section it rests on; calculations show the arithmetic.
You can skip questions, go back, change answers and mark questions to revisit before you submit. The clock keeps running in background tabs and reloads; when time runs out, your answers are submitted. Use a basic calculator: PSI provides one at the test center.
