Learn the job. Pass the test.
ClassMetric teaches the knowledge part of job certifications: five-minute story lessons with questions inside the story, then practice exams that explain every wrong answer. It's made for people studying on a phone between shifts, on the bus or at 5 a.m.
Who we are
ClassMetric is made by Winding AI, Inc., a small US software company. We run it from the United States, for learners in the United States. It launched on November 13, 2026.
Who it's for
Adults in the US studying for the written part of a job certification or licensing exam. You need to be 18 to make an account. We cover what the test asks, not the training some credentials also require: the BACB's 40-hour RBT training, your employer's hands-on forklift training and evaluation, or FMCSA's entry-level driver training.
Where it runs
In your browser at classmetric.com/app, and on Android through Google Play. The iPhone app isn't in the App Store yet. Sign in on any of them and your classes are there.
How lessons are made
- From the source. Each class starts from the official outline for its exam and the regulations and manuals behind it. We write down the facts each lesson relies on, with citations.
- Written with AI, checked against the source. AI writes the lesson cards and questions with the source text in front of it, never from memory, and every lesson is checked against those facts before it ships.
- Original questions. We never copy exam questions or reproduce code books. Questions are written to the published outlines.
- Never from memory. We tested 16 models: from memory, none passed.
- Still, check. AI can make mistakes. If something looks wrong, tell us at hello@classmetric.com and we'll fix it.
What ClassMetric isn't
We're independent study help. We aren't a school, a testing body, a licensing agency or your employer, and we aren't affiliated with any of them. ClassMetric doesn't replace hands-on training or an employer's evaluation, and passing isn't guaranteed. Each class page says exactly what it covers.
Comparing your options?
We wrote up how RBT exam prep options and IBEW aptitude test prep options compare, including when another one suits you better.
