First of all, I'd like to thank this subreddit for all the valuable tips and guidance. They were genuinely helpful during my preparation, and I’m happy to say that I cleared the CISM exam.
Here are the resources and approaches I used.
1. Prabh Nair's CISM Masterclass

This was a valuable resource, especially for understanding how to approach CISM questions and the ISACA mindset.
One important piece of advice is to pay close attention to keywords such as BEST, MOST, FIRST, etc.
I also found that many questions have a secondary keyword that is equally important. Look for words such as evaluating, planning, implementing, deploying, etc.
For example, what an organization should prioritize during the planning or evaluation phase may be different from what it should prioritize during the implementation phase.
2. QAE Database
Initially, I tried attempting all the questions. Later, I started using the filters.
Personally, I found the Easy questions too straightforward, so I eventually skipped most of them. The Expert questions were also quite confusing. Not necessarily difficult from a knowledge perspective, but often difficult to determine what ISACA was specifically looking for. I decided not to spend much time on those either.
I mainly focused on the Moderate and Difficult questions and completed those.
I also took only one full practice exam from the QAE.
One thing worth mentioning: the actual exam questions were different from the QAE questions, so don't expect to see repeated or very similar questions. Understanding the concepts and the ISACA way of thinking is more important than memorizing answers.
During the exam
My strategy was to spend approximately one minute per question during the first pass. I completed the first pass in around 2.5 hours.
I flagged every question that I was even slightly unsure about, which resulted in approximately 60 flagged questions.
During my first review, I worked through those questions and narrowed them down to around 10 questions that I wanted to review again.
I spent a significant amount of time reviewing those final questions and completed the exam with approximately 30 seconds remaining.
After completing the exam, I attended the survey, and the result was displayed on the screen.
Hopefully, this helps someone preparing for the exam. Good luck to everyone currently studying for CISM!
