How this academy works
Each lesson is short and hands-on. Mark a lesson complete when you're done — your progress is saved to your profile, and your team can see how far the group has come.
When you reach the lab lesson, you'll practice right inside the page: write your query, press Check my work, and get instant feedback on each exercise — hints included if you get stuck.
