I wish there were more specific pictures to what the slide were talking about. It would be easier to understand and benefit from the course f the details described in text were actually shown in the picture. Having videos that present the material would be even better. Initially I was interested in sdeing how complex scaffolding systems are built, how to secure them and etc which wasn't talked as much as I'd like to. And seeing that in video or pictures would have been beneficial. I have to admit, I didn't like the course and I wouldn't have done it if I knew what it actually teaches. I'd like to learn more about building techniques and various complex systems built around buildings. Thank you for the work you put into it
