Personally, I found this course more dense than the previous courses. I would have liked to have seen more visual descriptions of the topics, e.g. cryptography. But other than that, great course :)

I appreciate all who tried their best to make this course, but it just didn't work out for me as well as i wanted. I feel like i didn't retain much information, and that a lot of words and topics were thrown at me so quickly. There were virtually no useful or practical things to do to help us learn hands on either. There were also a lot of things that were not explained properly in depth and that are skimmed over. There are even things mentioned in previous lessons or sections that we don't learn about until much later, but is also glossed over a bit. I dont mean to bash the instructors and the other people behind the scenes who put this together, but at a certain point, i honestly just downloaded the text from the videos to teach myself better. Some videos is someone just reading the text with no prompts or diagrams for 7+ minutes, and videos that have prompts are...almost useless to be honest. I appreciate the attempt at diagrams, but they're not really useful to follow along that much. Anyway, there's more to unpack but my fingers hurt lol. There was some good, like i learned a lot of cool stuff, even tho little portions of the information wasn't useful to my graded quizzes. I hope this course works out for any others that wanna try it. its good to get your feet wet in IT.
