Hey everyone, glad to have you here. A few notes before you dive in:
- The course is built around 15-minute lessons. You can finish one on a coffee break.
- Each lesson has a role tag (BA, BI, DA, AE, DE, DBA, BE, MLE, PE). The planner already hides lessons that don't apply to your target role — but you can always reveal them in Settings → Lesson visibility.
- The sandbox runs each query inside a transaction that gets rolled back. You cannot corrupt the dataset, so experiment freely.
- If a hint isn't enough, ask the AI tutor inside the lesson, then post here if you're still stuck.
Have fun.
