As a total beginner in this field, I feel like I couldn't follow entirely with all the terms. I recommend adding to course information which courses are recommended to follow before this one. Furthermore, the location of the exam within the course should be changed, as already suggested in the comments. Lastly, I wasn't fan of how the videos had various styles instead of sticking to one style, and the last video also repeats information that was taught in an earlier video. It would be good to pay attention to this sort of things when making changes to courses. Overall, I did learn a lot of new things in Excel. I could follow it relatively well considering I have no background in this field.
