CSLB Class C-10 — Electrical (Trade Exam) Cheat Sheet PDF (2026)

Yes — it is a PDF, which opens on phones, tablets and computers and prints cleanly. There is no EPUB edition of this one.

Start with what costs nothing: 521 practice questions on PrepPass, with explanations and no signup. If you want it taught in one file you keep, the full study guide is $14.99 once; the printable cheat sheet for the last days is $9.99. No subscription on any of them.

You can retake it under Contractors State License Board (CSLB), California Department of Consumer Affairs's rule: CSLB gives you 18 months after it accepts your application to pass; within that window you may take an exam as many times as you need, but you must wait 21 calendar days after each attempt. Confirm the current policy with Contractors State License Board (CSLB), California Department of Consumer Affairs before you book.

Contractors State License Board (CSLB), California Department of Consumer Affairs — exam delivered by PSI Services LLC. CSLB's legal existence is set by Business and Professions Code § 7000.5. CSLB states it has contracted with PSI to administer its examinations.

Not published by CSLB. CSLB says only that “All trade examinations consist of multiple-choice questions.” No count appears in the study guide, the Examinations FAQ, or PSI's candidate bulletin.

210 minutes. CSLB: “You will be given 3-1/2 hours to complete each examination.” It is per examination, not per sitting — a candidate taking Law and Business plus a trade exam gets 3-1/2 hours for each.

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.

$450 — Original application (exam or waiver, one classification) (CSLB, one-time); $51.43 — Examination registration (each registration, first attempt or retake) (PSI Services LLC, per attempt); $200 — Initial license fee (sole owner) (CSLB, one-time); $350 — Initial license fee (non-sole owner: partnership, corporation, LLC, joint venture) (CSLB, one-time); $20 — C-10 electrician-certification surcharge, added to the active license renewal fee (CSLB, per renewal). Two payees: application and license fees go to CSLB, the per-exam registration fee to PSI. CSLB's 2023 “Get Licensed to Build” PDF still names a $100 rescheduling fee; it appears neither on CSLB's current fee list nor in Business and Professions Code § 7137 as amended effective 1 January 2026, so it is not stated here. The application fee is charged once per original license application and covers both required exams.

English. CSLB names ten exams that have Spanish versions and C-10 is not one of them, so the C-10 exam is English only. For other trade exams and languages CSLB may allow an approved translator as an accommodation. CSLB does publish a Spanish C-10 study guide — that is a study guide, not a Spanish exam.

None of it needs this cheat sheet.

No. This is an independent cheat sheet and is not affiliated with or endorsed by the exam's awarding body.
