lrnitFor analysts

Learn SQL in a course built only for you — and actually retain it.

Go from spreadsheet exports to writing your own production queries: joins, aggregations, window functions, and the query patterns behind real business reporting.

Built around your goal — not a catalog

What your course could open with

lrnit interviews you first — what you know, why you’re learning, how you think — then generates every lesson for that. Sample lessons from a course like yours:

01SELECT, WHERE, and the mental model of a table scan
02Joins without fear: inner, left, and the duplicate-row trap
03Window functions: running totals, rankings, and month-over-month deltas
04The cohort query: retention analysis you can re-run every Monday
…and the rest is generated for you: your gaps, your pace, your job.

Measured, not watched

By the end, you’ll be able to

Answer your own data questions without waiting on engineering
Write joins and window functions that are correct, not just plausible
Build reporting queries your team re-runs every week

Every lesson ends in assessment. Mastery is tracked per concept with spaced review, and the course adapts to what you actually retain — finishing means a timed final exam and a verifiable certificate, not a completion badge.
