I take tons of certification classes, test preps, and tests. For the exception of one class out of the 15 I took for my Bicsi RCDD, the CISSP self paced course is one of the worst classes to spend money on. It is very tiring to rate your understanding of the content each time. There is no, to little written content which is the primary way I learn. I literally had to listen over and over again to take notes or pull from the transcript. I wish they would give Chapter 1 review so you could understand my frustration.
I didn't finish the course because I thought it was so bad. I am switching to training provided by Pete Zerger and Mike Chapple.
I finished the Certified in Cybersecurity which I thought the training was good.
I thought the opposite of the training having recently used it to become CISSP certified and covered 100% of the content (Not just stopping at competency in the module).
Coming from taking numerous Microsoft and CompTia self paced training which is primarily reading, I've come to appreciate the change of pace which a mix of videos, reading, and quizzes bring. I find Salesforce trailheads also does a good job with their training which throws in active Sandbox training as well.
I suppose what I'm getting at is everyone learns in different ways! I'm sorry you needed to find out the rather expensive way that the ISC2 self paced training isn't your style but I found it refreshing and rather enjoyed it!
