In reflection of what you did today, you simply report that you made a simple tracker and dashboard on Excel for data you are trying to record regarding your reviews for the licensure exam.
Did you procrastinate? Perhaps. Was it worthwhile? Probably not. Regret? Probably. However, you did realize today that Microsoft Excel is the ultimate end solution for storing, processing, and analyzing data for internal use. It's widely available, practically everyone knows how to use it, and less time-consuming to set up something working than a full-on dashboard using Python or JavaScript.
