For those interested in Excel and Google Sheets, I recommend checking out the course at Eduson Academy. Its cost is comparable to the prices of individual Excel courses at other institutions, but here Google Sheets is also covered. This way, you get two courses for the price of one (although, to be honest, it's more like one and a half courses since Google Sheets is mostly studied at a basic level). The program is suitable for almost beginners, but you need to know the basics of working with Excel, such as creating a new document, changing fonts, and performing simple mathematical operations. More complex topics, like VLOOKUP and SUMIF functions, are covered during the course. The sections dedicated to Google Sheets mainly cover unique features that are not available in Excel. In principle, since both use spreadsheets, a separate course on them might not be necessary. Among the more advanced topics, macros and interactive dashboards are studied. I also want to highlight the practical sessions in the course. I expected that we would just be doing calculations in Excel, but the practice took place on a special simulator that actually mimicked Excel. It had step-by-step instructions and tips, which contributed to a quicker understanding of the theory.
