Regardless of your job, it explains only the essentials that you need to know in an easy way! I highly recommend it! I like this lecture because it teaches you the 'know-how' rather than the 'hard work' of data management. Please take an Excel lecture from a professional instructor like this! A person who was famous for being good at Excel at work became famous as an Excel YouTuber and created a lecture to sell it, but I was so disappointed when I took that lecture. It was a lecture that tried to teach you too much at once. It was as if he was saying, "I know how to do all this, I know all these functions." He even teaches you the functions that are only necessary for specific jobs.. I recommend this to those who don't want to know all the functions and features of Excel.
