Knowing the material is the most important part of passing your California contractor licensing exam, but having a good test-taking strategy can help you use that knowledge more effectively.
CSLB contractor exams are currently administered by PSI as computer-based, multiple-choice examinations.
Each question gives you four choices, and your job is to select the BEST answer.
CSLB currently gives you 3½ hours to complete each examination, whether you’re taking Law and Business or an applicable Trade exam.
Here are some strategies to help you use that time effectively.
Older contractor exam advice sometimes refers to a:
Don’t build your strategy around those numbers.
CSLB does not publish one universal question count or passing-score percentage that should be treated as the rule for every contractor examination.
Instead, concentrate on answering as many questions correctly as possible.
Your specific CSLB Examination Study Guide is the best source for the current topics and approximate weighting for the examination you’re taking.
When you encounter a question you can answer confidently, don’t overthink it.
Read:
Then choose the BEST answer.
CSLB specifically advises candidates to read each question and all four choices completely and carefully.
Sometimes more than one answer may initially seem possible, but you’re looking for the best answer based on the information provided.
You have 3½ hours, but that doesn’t mean you should spend an excessive amount of time wrestling with one question.
If a question is difficult:
If the testing interface allows you to return to the question later, you can reconsider it if you have time remaining.
The goal is to avoid allowing one difficult question to interfere with your ability to answer questions you know.
If you don’t immediately know the answer, start eliminating choices.
For example, if you’re reasonably confident that two of the four answers are wrong, you’ve significantly narrowed your decision.
Look for choices that:
Then choose the best remaining answer.
This is one of the most important CSLB test-taking rules.
There is no penalty for guessing.
CSLB specifically advises that if you’re unsure about a question, it is better to answer it than leave it blank.
So even when you’re uncertain:
A blank answer cannot help you.
An educated guess might.
Read questions closely.
Words such as these can completely change what the question is asking:
For example:
Which of the following is required?
is a very different question from:
Which of the following is NOT required?
Missing one small word can turn an easy question into a wrong answer.
Don’t immediately select the first answer that sounds correct.
CSLB’s official study guides specifically instruct candidates to read all four choices before selecting the BEST answer.
You may see:
That’s why reading every option matters.
Each CSLB examination currently gives you:
3½ hours
You should have enough time to work carefully, but you still need to manage your pace.
Don’t rush through easy questions unnecessarily.
At the same time, don’t allow one calculation or unfamiliar question to consume a large portion of your testing time.
During your exam preparation, use timed online practice exams to develop a comfortable pace.
Good test-taking strategy cannot replace studying.
CSLB publishes official study guides that identify the major content areas and approximate weighting for each examination.
For example, the current Law and Business examination covers seven areas:
The percentages are approximate.
Your Trade examination will have its own classification-specific breakdown.
Use those percentages to guide your study preparation, not to decide which questions you’ll answer on test day.
Before the real examination, practice tests can help identify where you’re struggling.
If your results consistently show problems with:
spend additional study time there.
Don’t spend all your preparation time reviewing subjects you already know well simply because they’re more comfortable.
Your practice-test results should tell you where your remaining study time will have the greatest value.
Don’t memorize practice-test answers.
If you remember:
Question 42 = Answer B
but don’t understand why Answer B is correct, you’re not prepared for the actual examination.
Instead, understand:
behind the answer.
The actual CSLB examination will contain different questions.
That’s why I always tell applicants:
Learn the answer, not the question.
Some CSLB examination questions require mathematical calculations.
A calculator is provided for the examination.
When working through a calculation:
If your calculation produces an answer nowhere near the choices provided, review your work before moving on.
If you review a question later, don’t change your answer simply because you’re second-guessing yourself.
Change it when you identify a specific reason that your original choice was wrong.
For example:
Randomly switching answers because you’re nervous can work against you.
A good practice test can help you practice:
But don’t expect a private practice test to contain the same questions you’ll see at PSI.
The goal is to become comfortable applying your knowledge to new questions about familiar concepts.
You can use our CSLB Online Practice Exams as part of your preparation.
Avoid these common mistakes:
Three and a half hours gives you time to read carefully.
One difficult question shouldn’t prevent you from completing the exam.
There is no penalty for guessing.
CSLB contractor licensing examinations are multiple choice, with four choices per question.
Learn the underlying concept instead.
Focus on mastering your material rather than trying to calculate the minimum number of answers you need.
CSLB currently provides 3½ hours for each examination.
Law and Business and Trade are separate examinations when both are required.
Current CSLB study guides state that examination questions have four choices.
You select the one BEST answer.
No.
CSLB specifically states that there is no penalty for guessing.
If you’re unsure, answer the question rather than leaving it blank.
Prioritizing questions you’re confident about can help you maintain momentum and prevent difficult questions from consuming too much time.
Regardless of the order you use, make sure you ultimately answer every question.
Don’t rely on a universal 70% or 72% passing-score claim.
Your goal should be to answer as many questions correctly as possible rather than trying to hit a presumed minimum threshold.
Don’t rely on a universal 115-question count.
Use CSLB’s current examination information and study guide rather than older fixed-count claims.
Some examination questions require mathematical computation, and CSLB states that a calculator will be provided.
Yes.
Current CSLB study guides describe the examinations as multiple choice with four possible answers and one BEST answer.
A good CSLB test-taking strategy is straightforward:
Most importantly, don’t walk into the examination calculating how many questions you can afford to miss.
Prepare to answer every question as accurately as you can.
