I’m very disappointed with this SQL course and honestly regret taking it. The overall structure felt rushed and poorly organised. Many of the videos were extremely short—sometimes just one or two minutes—and often lacked clear explanations of what was actually happening. There were no additional materials to support the learning process—no readings, no substantial exercises. Everything felt overly simplified and “dumbed down,” which made it unhelpful for anyone with even a bit of prior experience. At the same time, the lack of clarity and structure would make it confusing for complete beginners as well. Another major issue was the delivery. The lecturer was quite difficult to follow—there were frequent long pauses, moments of uncertainty in explanations, and an overall impression that the material wasn’t well prepared before recording. This made it hard to stay engaged and focused throughout the course.
