Every practice test tells you the right answer. This one tells you why the answer you picked was wrong. That is the part that changes what you do next time.
It exists because a customer asked for it: a dad with a one-year-old, a nine-to-five and side work, who learns by doing and does not have an evening free to read lessons. He has six minutes. So a session is ten questions, there is no timer, and if the baby wakes up halfway through it picks up exactly where you left off.
Before you answer, you tap how sure you are. Getting one right while guessing is not knowing it, and most apps quietly mark that as learned. Here it is what brings the question back in a couple of days, while the ones you actually know get out of your way.
A complete study platform built specifically for the C-36 exam. Master the material, pass with confidence.
Comprehensive coverage of all exam topics from underground plumbing to California codes.
Listen and learn anywhere: every lesson has a narrated version, 14+ hours in all.

Two separate CSLB examinations. We cover both.
Closed book · CSLB weighting
A separate CSLB exam · required for every classification
Passing gets you a license number. Then you are a business, and the rules that suspend a license have nothing to do with the exam. We wrote the 102 lessons, worked cases, and fill-in templates we wish someone had handed us, each dated to the California law it describes.
$1,000 or 10%
A home improvement down payment cannot exceed $1,000 or 10 percent of the price, whichever is less. Taking more is a citation on the first complaint. Our contract template has the cap and every required notice printed in.
Jan 1, 2028
The exemption most one-truck shops sign ends. CSLB must be verifying exemptions by January 1, 2027, and a lapse suspends the license by operation of law on the day coverage ends. The calendar template puts both dates on your wall.
4 and 10 years
A customer can file with CSLB four years after the work and ten for a latent defect. The job folder is your defense, so the retention lesson tells you what to keep and for how long.
From pass letter to license number

Fair question. Classroom courses and private tutoring cost a lot more than this. So what is the catch? There is not one, and here is the honest reason it costs this little.
We are a small team, not a big company. We are not spending hundreds on ads to sell a $149 course, so we do not have to charge several times that to make the math work.
This is the Workforce Initiative price on purpose. For a lot of good workers, the thing standing between them and their own license is a prep course they cannot justify. We would rather price it so anyone serious can afford to get licensed.
And we are betting you will tell somebody. Every plumber who passes and mentions us to the next person on the crew is worth more than squeezing an extra few hundred out of you today.
That is the whole deal. Pay once, own it forever, and we put our money where our mouth is: if it is not for you, email us within 14 days and get every dollar back (that is for people who tried it, so it applies before you have done 5 lessons or used 20 AI tutor messages). Or do the work, finish every exam-prep lesson, score 85%+ on three full practice exams, sit the real C-36 within 6 months, and if you still do not pass, send us your CSLB result letter and we refund every penny. All we ask in return is that you actually use it.
Everything you need to know.
