    I like all the business problem solving cases, really help with understanding the code and also helpful in interviews. The examples are explained really well and the practice are relevant.

    This was an excellent hands-on course. The problems were challenging and did a great job of simulating real-world business scenarios. It really forces you to think beyond basic syntax and understand the logic of what you're asking. The exercises on multi-level aggregation (like finding the average of monthly totals instead of individual sales) were particularly valuable. I would definitely recommend this to anyone who knows basic SQL and wants to learn how to apply it to solve actual problems.

    It would be helpful to include a downloadable database file for hands-on practice alongside the instructor. I’d love to see future integration with GitHub Codespaces to ease learners’ practice experience. Some instructions and database fields vary slightly—for example, one challenge references a field name that doesn’t match the relevant table. It would also be great if the instructor could briefly explain functions used in challenges that aren’t covered in the lesson videos.
