The homework actually uses real tables
Course: SQL for analysts · Rating ★★★★☆ · Course average 4.4
Six weekly sets, each built on a public transit dump. You write joins that fail on dirty keys, then you fix the keys. The lecturer posts a short note after each deadline with the three mistakes that showed up most. Office hours are Thursday, in person, and the queue is real.
I came from spreadsheets. Week three forced a window function I still use at work. The final is a take-home: rebuild a delayed-bus report and write why the numbers lie. I would take the advanced section if they open it in spring.
