The problem

Why most exam prep fails

💸

Overpriced courses

Most CSLB prep programs charge $295–$1,195 for material you could learn in a fraction of the time.

😴

Boring, dated formats

Thick textbooks and desktop-only programs built in 2010. Nobody wants to study that way.

🤷

No way to know if you’re ready

You finish a course and just... hope? There’s no signal telling you when you’ll actually pass.

How it works

Three steps to exam day

Practice real exam questions

200+ questions covering Law & Business and Trade — written to match what you’ll see on test day.

We target your weak spots

Our adaptive engine analyzes every answer and focuses your study time on the topics you need most.

Know when you’re ready

A pass probability score tells you exactly when to book your exam — no guessing.

Built for the jobsite

Study between jobs, not instead of them

“I studied on my lunch break for three weeks. The app told me I was at 85% pass probability. I booked my test, walked in confident, and passed.”
