If you're prepping for the CTS-D exam, this book is like that friend who knows all the answers but makes you work for them. It doesn't spoon-feed you—expect to wrestle with concepts and apply math to real-world scenarios. Memorization won’t cut it here, but if you put in the effort, it pays off.

Now, let’s talk typos. Yeah, there are a few, and some even mess with the accuracy. But here’s the kicker: those same typos pop up on the actual test. So in a weird way, this book’s flaws might actually prep you better. Just don’t skip the practice math—trust me on this.

The organization? Solid. It’s not just an exam crammer; it’s a reference you’ll keep pulling off the shelf for real projects. Diagrams and pictures are helpful, though I wish they were in color—it’s 2023, people! Still, for AV calculations and concepts, it’s a lifesaver.

Delivery drama aside (shoutout to honest neighbors), this book does what it promises: gets you ready for the test and beyond. Just don’t expect a leisurely read—it’s dense, practical, and occasionally frustrating… kind of like the AV industry itself.
