A friend of mine first recommended Thor’s CISSP video series on Udemy and I was glad that he did! The course content was fantastic and to the point, and the real-world examples it provides helped me synthesize and apply the information. Also, a special shout out to the essential information elephants! (You’ll know what I mean). This resource was by far my favorite video series that I utilized in my successful studying for and passing of the CISSP exam in May 2020. Thank you for the fantastic content!

I am not sure what else there is to say that has not been said about Thor. You can tell he has a passion for teaching and really does care about his students. His videos are short and to the point which is wonderful for courses like CISSP which has such a large scope it makes it frustrating at times. Thor’s material is a breath of fresh air, and I can say without them I may not have passed. Thank you, Thor!
