Much of the content was already presented by the previous course (Introduction to Cybersecurity Tools & Cyber Attacks). Video quality is horrible and some slides content is unreadable even at max quality setting. It points to good resources, however, and the last weeks content was ok.

Course explanations were well written and informative. However some of the images and transcriptions were abysmal quality and a few of the quizzes actually had incorrect answers, such as the "What bit version of Windows10 can you purchase" question.

I have given this course but the mentor for CIA was not that much impressive for knowledge sharing. His voice seems he was already tired before session in short no energy in delivering the knowledge.
