Progress Tracking

Select Star SQL includes a progress tracking system that helps users monitor their learning journey. As users complete lessons and exercises, their progress is recorded, providing a clear overview of what they’ve accomplished and what remains to be covered. This feature is particularly useful for maintaining motivation and ensuring consistent progress.
