Pass the Law & Business exam.

Every contractor in California takes this one, whatever your trade. Drill the real questions until they stop surprising you — and every one of them comes with a written explanation of why the right answer is right, and why the tempting wrong one is tempting.

What you get

No videos to sit through. No textbook. Just the questions, and a straight answer on every one.

2,037

Practice questions

Every section of the Law & Business exam and the B trade exam, cut into short sets so you're never staring down a wall of 99 questions.

Every one

Carries a written why

Not just the right letter. Each explanation says why that answer is right, and why the one you nearly picked is there to catch you.

Twice

Your punch list

Everything you get wrong lands on one list and keeps coming back until you've had it right twice running. Same as any other punch list — a list of things to fix.

What failing actually costs

A retake isn't just the fee. It's more weeks before you can pull permits, sign contracts in your own name, or bill as a licensed contractor — weeks of work going to somebody who already has their number.

Most people don't fail Law & Business because it's hard. They fail because they read a book once and never drilled the questions.

How it works

Step one

Sign in with your email

We send a 6-digit code. No password to make up, and none to forget.

Step two

Pick a section and go

Fifteen questions a set, about nine minutes. Answer, read why, move on.

Step three

The ones you miss come back

They go on your punch list and stay there until you've had them right twice. You don't have to remember what caught you out.

Two ways in

Getting licensed means passing Law & Business and the trade exam for your classification. Take the one you need, or both.
