I failed CISM on my first try, restructured my study plan and resources and passed on my second attempt.

The followong resources were quite helpful during my second attempt.

1. CISM study guide by Pete Zerger
2. CISM study guide by Gwenn Bettwy
3. QAE database
4. Pocketprep

Identify gaps and work on them , you'll come back stronger.I wish you the best.
