Passed the CISM exam yesterday! It took about 3 hours to complete and review everything I had flagged. I didn't feel at all rushed and the difficulty was on par with the questions seen in the QAE DB. It's a very useful tool and I highly recommend using that until you're comfortable with the level. I was scoring about 80% prior to taking the exam.
I also read the CISM Review Manual. It's very dry and a little verbose, but it does provide plenty of useful material and will get you familiar with ISACA's view of the world, which is crucial to passing the exam.
Next up...might try one of these cloud certs
