how it compares

Not a school course

A school sells a full package — classes, materials, a schedule, sometimes help with the application — prepaid for a fixed term. LICENA is a question bank with written explanations and sources: monthly, cancel anytime, in EN · ES · RU. If you fail the real exam, CSLB lets you retake it after 21 calendar days and PSI charges the exam fee again.

FAQ

What you're thinking right now.

Is LICENA free?
Registration and the free-tier exams (EPA 608, OSHA, asbestos, NICET, backflow) are free. Every paid bank starts with a one-time 3-day free trial (no card), then $9.99 for your first month and $19.99/month after — cancel anytime; your progress is never deleted.
Are these the real exam questions?
No. Questions are written from scratch in the format and difficulty of the real exam, based on official public sources — never copied from the actual exam.
What languages is it in?
The interface and study content are in English, Spanish and Russian, with a bilingual side-by-side study mode.
Is this just memorizing answers?
No. Every question is explained through the real situation behind it: why that answer, which code or formula stands behind it. You pass the exam and understand the trade deeper at the same time.
Will LICENA guarantee I pass?
No. LICENA is a practice tool, not a school, and does not guarantee passing. Real exams also draw on sources beyond our banks.
Which exams does it cover?
California: CSLB Law & Business and the trade exams A, B, B-2, C-7, C-8, C-10, C-16, C-20, C-27, C-33, C-36, C-39, C-46 and C-54. Arizona: SRE, B, R-11, R-37R, R-39R. Nevada: CMS, B, B-2, C-2, C-21. Louisiana: Business & Law, Building Construction. Plus EPA 608, NICET fire-alarm and water-based systems, backflow prevention, OSHA construction safety and asbestos.
Is Law & Business included with a trade bank?
No. Each paid bank is a separate subscription — $9.99 for the first month, $19.99/month after. The free-tier courses — OSHA construction safety, EPA 608, asbestos, NICET, backflow — come with any account.
Does the 8-question sample show whether I'm ready?
No. It shows the format and how the explanations work. Eight questions are too few to judge readiness for a state exam. The timed mock in the full bank is a better check — and even that is practice, not a prediction.
