LuLu1 - Congratulations!
I did this exam yesterday and so dissatisfied with isc2 majority of the courses taken were not aligned with the exam I took yesterday. I was prepared for what they taught during the class and was disappointed to see something different entirely during the exam. A friend who wrote the exam also confirmed the same thing. I think it’s better to use YouTube video to study rather than relying on isc2 studies
