While taking the course, there was a significant difference between the program the instructor was using and the free version, and it wasn't updated accordingly, which made this a really disappointing course. I had to spend more time fixing error issues than actually learning about data. It was such a disappointing course, and it would have been better if the instructor had taught using the same environment as the students (free version, etc.) and provided explanations for the errors that occur. I was really stressed over the weekend 😭
