Are you using indexes made by someone else or did you make it yourself? I highly suggest doing it yourself so you're more familiar with the layout and how your brain seeks content. I had tons of duplicate entries because search context matters. One question may ask what HTTP response code 301 indicates or it may ask what response code is returned when content has been Moved Permanently. Don't rely on memory to differentiate. Figure out how you'd begin looking the answer up and make sure it's covered in your index, then do it again for any other contexts you can think of.

I used this Lesley Carhart post as the basis for creating my index.

You're right that there's an untenable amount of knowledge if you're relying on your memory to get through it. Much like working in the industry, you don't have to have encyclopedic knowledge on any topics, but you do need a reliable method to find answers. I literally went page by page building my index over the course of a week. The prep was well worth it because not only did I have a solid index, I had gone over every piece of material shortly leading up to my test.

I did almost get blind sided by the clock though. I finished with about 2 minutes left. Please do also keep in mind certs are not remotely necessary. There's a person on my team that has zero certs but runs circles around me during forensic investigations.
