Welcome — how to get the most out of this course

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.

Question — I see lessons marked DEEP for my role. Do I have to do them?

DEEP is opt-in. CORE + IMPORTANT is the recommended path. Tackle DEEP after you finish a module if you have time and energy.

Is there a study buddy thread?

Not yet — feel free to start one and we'll pin it.
