By Sadie Powell on 1/9/2022
most of the topics are a refresher to me. But explained in a more down to earth way that I can use in everyday life. Most instructors in a college setting do not go into this much detail that is easy to follow. This class is turning out better than I expected This class is helping me advance my Cyber Security and I am so glad that I found this course and I enjoy learning from Henrique Centieiro Thank You for the opportunity to learn from you
