When I first heard it, there were many reviews saying it was difficult because it mixed English, but I think it was because I was not familiar with Terraform. I thought I would just skim through it and then went straight through it, and it seemed like the basics were laid out easily, so it was quite good. If there are people who are starting the lecture after reading the course reviews, rather than thinking about understanding all the concepts from the beginning, I think it would be good to watch it all first and follow how those concepts were created to be used :)
