20 project paths. 200 hands-on activities.
Every path ends in something real you can show: a checked report, a working page, a tested model or an honest offer. Each activity follows the same loop — read a short explanation, do the task with real files, check it, then ship.
- ReadOne idea, one worked example
- DoA task with real practice files
- CheckExpected results and common mistakes
- ReviewSelf-check questions
- ShipA capstone with a rubric

Questions people ask
Is the Academy really free?
Yes. Every path, handbook and practice pack is free to read and download, with no signup. An optional free account only syncs your progress between devices.
Do I get a certificate?
No. Open Practice is not accredited, and self-review is not assessment. You leave with something better for most employers and clients: a finished project and the evidence that it works.
Why did some courses disappear?
Overlapping paths were merged so nothing is taught twice. Your saved progress moved with them automatically, and old links redirect to the new module.
Do I need an AI subscription?
No. Activities work with free tools, your own free API key, or no AI at all. The practice files and expected results let you check your work either way.
