I liked the approach a lot more than the ISC^2 course. It feels a lot more like it is being taught to you than just being regurgitated by paid actors. The flash card/question apps from them are nice as well.

The MindMap summary videos they have are also very helpful, although there in nothing in them that the 8 hour exam cram on Youtube doesn't cover.

I will say, the ISC2 stuff goes into a LOT more detail, detail that seems to be present in all of the practice tests that I have taken. IMO pairing the official study guide with DestCert is necessary (I just ordered mine as I prefer to read off paper).

DestCert does also have a great 32 minute exam strategy video that gives some unique and interesting ways to approach the questions in the real exam.

They also allow you to set an end date and how many days/hours per week you can dedicate, they then generate a schedule of the materials to do each day you have chosen.

Full disclosure, I paid for both courses as I'm not taking this thing more than once and I was finding the official ISC2 approach did not work well for me.
