If someone with no knowledge of how to make a spreadsheet tried to learn from this, they would be lost. The instructor really failed to explain what different parts of the formulas meant. While I was typing a formula in, the instructor video would just take over my screen. The workspace wouldn't allow me to even use the copy and paste options and the keyboard shortcuts would only work half the time. I couldn't even save the spreadsheet she instructed me to make because the options weren't available. Despite attempting to download the extensions the workspace browser would prompt, it just wouldn't work. If you don't have patience and a basic knowledge of spreadsheets, it might be best to look elsewhere.
