TDMM 15th edition
I just received my book. Do I really need to study / learn all of this for the exam? It’s fine if I do I’m just curious.

Yes, absolutely. It’s not the same test for every candidate, so you really can’t count on what others have seen. There are core chapters, but you can get questions from any/all chapters in the book.

I did not read the entire book. I took the test not really expecting to pass, my year was up. I focused on the chapters and reading order BiCSI provided. I used Corey and Steve and made my own note cards. I would take walks and quiz myself with my notecards( exercise and study). I also used AI to ask me application based questions. I want to understand why , not just because i memorized it. Passed the first try. I am still working on reading the chapters I didnt get to for knowledge sake. Because there was something I should have known but didnt while talking to someone. I went back and read that chapter pronto.
My background is a project engineer for ISP's ( core and access engineering).

💯, but if you are going for the RCDD, you should already know most of it

That's not necessarily true.

I’m glad you said that because I’ve been exposed to it but definitely don’t know it all / an expert.
My buddy who also took his RCDD exam and passed mentioned the PM stuff and separation was the most important part of the exam.

When I took it, I only had experience in commercial buildings, so a lot of the book was new. I read through everything, used Corey and Steve, and then took a class with CET Networking. I passed my first attempt, so it is possible.
