CMP exam coverage: how deep does it go on mixing vs mastering distinction?

I want to know how the CMP draws the line between mixing and mastering content on the exam. As someone with a strong audio engineering background I find mixing and mastering are covered in very different depth by different certification programs — some treat mastering as a brief overview while others expect you to know specific LUFS targets, true peak limiting, and loudness standards for streaming platforms.

For the audio recording certification side of things I'm fairly confident — gain staging, mic placement, room acoustics, signal chain setup. But I'm curious whether the CMP exam treats mastering as a separate competency domain or rolls it into the general mixing and post-production section.

I found the CMP Audio Mixing Techniques practice quiz to be solid prep for the mixing domain. Questions covered EQ curves, compression ratios, stereo width, and bus processing — all practical and well-framed. I haven't found equivalent mastering-specific practice material. If anyone has notes on what mastering topics showed up in the real exam, that would be extremely helpful for my final prep week.
