Negative Feedback

  • I’d say the problems available in this course were too basic and short as well. Also, I feel like there aren’t enough examples in the course. I would have given a 5-star rating to this course if the instructor had gone into more detail while describing the functions and commands (Tim Rock, ★★★☆☆).
  • The title is not what the course actually is. The course didn’t meet my expectations at all. Whatever the instructor explained was too basic and impractical for any business (John Wilde, ★☆☆☆☆).
