How do you start?
Read the public guides without signing in. Practice workspaces and personal learning records require a learning account. Access to particular materials and downloads follows the conditions shown on their pages.
Materials, sources and review scope
This is a project-built learning site. Some teaching text and illustrations are created with AI assistance. Material pages explain their rules, sources and review limits; specialist footage follows its own source notes. Practice and self-assessment are not professional certification.
Common questions
Who is it for?
It is for learners exploring data annotation and AI evaluation, including those continuing with basketball, tennis or film material. Check each task’s rules and prerequisites before starting.
Which languages are available?
The interface and public guides are available in Chinese, English and Spanish. The language, scope and readiness of individual learning materials are stated on their pages.
Does completing practice guarantee paid work?
Practice develops judgment and produces reviewable learning work. A practice result is not a job offer, an income promise or professional certification.
How can I report a material or rule issue?
Follow the help page’s feedback instructions. Keep the page URL, material and version, the specific rule and your evidence, then share them with the person who invited you to try the site.
