Hi all,
I’m currently working on improving my SQL skills to align more closely with the kind of work data analysts actually do on the job — things like querying large datasets, cleaning data, building reports, and handling case-based scenarios.
While I’ve gone through beginner tutorials, I’m now looking for free platforms or projects that offer hands-on practice with realistic datasets and challenges — not just textbook-style questions, but the kind that simulate real business problems or dashboard/reporting tasks.
What free SQL resources or platforms would you recommend that closely reflect the day-to-day work of a data analyst?
Bonus points if it includes mock company databases or case study-style problems. Appreciate any suggestions, and thanks in advance!
