Six hours. Most people who think they can skip this cannot, and the placement test says so kindly.
Eight hours. Joins, groups and the four queries that cover ninety percent of real work.
Nine hours. What an average hides, and why your dashboard is lying.
Twelve hours. Pandas, and stopping before it becomes a software course.
Five hours. The stage that gets people promoted, and the one everybody skips.
Open-ended. One question, one dataset, one page. Reviewed by a human.

Stage five is about explaining your answer to somebody. It is the only reason anyone at work noticed I had done any of this.
