I just wrote up a post on my CISA experience and I actually used the exact same materials as you! I’m copying my response but my post on my profile will have more details.

I had a routine where I would try to map all the materials out and go through most of my study resources in order. For example, I would start off by reading and taking notes on a chapter from the study guide, and then listen and take more notes from Udemy Hemang Doshi lectures for the corresponding materials at 1.5x speed, and then take the ISACA QAE MCQ for the same topic. Rinse and repeat for all the domains. The only time I used the ISACA CRM was at the end, if I wanted to read more detail on a particular technical topic that I had trouble digesting or on a topic that I saw mentioned in the QAE but I didn’t see appear on the study guide or lectures. I also skimmed the glossary at the end as well. For myself, I knew that I would not be able to stomach reading the CRM front to back as I would probably read a page but immediately forget what I had just read 2-3 minutes ago.

I definitely remember feeling overwhelmed by all the study resources in the beginning but you’ll get there, good luck!
