Rounded up from 2.5 stars. Starting as a complete beginner, I feel I learned a lot, but it required significantly more time than estimated, and a lot of self-teaching and trial-and-error.
The amount of information provided in the five-minute videos would be more useful in a bulleted list - way too much to digest in such a short time. Someone really needs to go through and edit these courses. There are a lot of obvious typos, and the way several sets of instructions are worded/formatted makes them unnecessarily confusing. Also, at least two answers in the quizzes are incorrect, confirmed by the "explanation" provided in the feedback provided post-quiz. I made a note of one of them: Self Review in 'Sorting Data', Q3. The first quiz contains questions on material that isn't covered until later modules, and instead of the ability to retake it three times every 24 hours, like all other quizzes throughout the course, you're only given one. I recommend skipping it until the third module is completed. I likely wouldn't recommend this course to those who don't have basic knowledge of formulas and functions used in Excel.
