Our Verdict
Advanced SQL: The Ultimate Guide (2025) is a comprehensive course covering advanced SQL topics and concepts, providing easy-to-follow materials. While it can serve as an excellent resource for certification exam preparation or advancing professional skill set, the course falls short in including practical exercises to solidify understanding of hands-on coding skills. Additionally, quizzes throughout the course contain errors that may contribute to confusion and misinterpretation for some students. To maximize learning potential, we recommend pairing this course with practice exercises or external projects to improve hands-on SQL skills.
