Course path
Analytics SQL Path
A focused path for metrics, period analysis, cohorts, joins, grouping grain, and executive reporting.

Who this path is for
A focused path for metrics, period analysis, cohorts, joins, grouping grain, and executive reporting.
- Audience: Analysts and product operators who need reliable metrics, cohort questions, and executive-ready SQL evidence.
- Prerequisites: Comfort with SELECT, WHERE, basic joins, and reading table grains.
Observable learner outcomes
The course states outcomes as observable SQL behaviors that can be checked through local attempts, hidden variants, reviews, and projects.
- Build metrics with safe aggregation, complete periods, and explicit numerator/denominator definitions.
- Explain cohort and retention queries with row grain, null behavior, and period boundaries.
- Produce project-ready reporting SQL with validation checks and caveats.
Estimated effort range
Estimated effort range: 14-22 hours. This is a planning range, not a fake guarantee; prior SQL experience, review spacing, and project depth change the total.
Cumulative reviews and project requirements are part of completion, so finishing the path means more than viewing lessons.

Reviews, projects, and mastery
Completion uses independent attempts, delayed review, transfer evidence, and project milestones rather than simple page views.
Cumulative reviews, project requirements, and final transfer checks are visible parts of the course contract.
Start with the full path, or use path-specific practice when you want a focused session.
Page highlights
- Ordered modules with realistic effort and transfer expectations
- Original exercises tied to SQL Trail datasets
- Cumulative reviews and independent transfer checks
- Projects, references, and practice routes for the path
