I liked how they explained everything very well, also it was easy for me because of my skillset as an IT security professional (a CISSP). It's not really anything negative about this course; however there were times when you could tell some students had prior knowledge or experience with programming/security topics which made them feel like "they" knew more than others who didn't have those credentials but still learned just fine from these courses! The way their team teaches makes learning so much easier since all information can be conveyed at once unlike other companies where sometimes only half your class gets any instruction time due to scheduling constraints etc...
