If they have never gone through the actual testing experience with PearsonVue, how will they answer those questions? We all know there is more to passing CompTIA certifications than knowledge. It is also the skill to be able to sit for the test and pass it. Regarding the wording, navigating PBQs, whether you get a calculator or not, what the setup is like, what the registration process is like, and whether you get your score right away, where do you go to reschedule, etc.
In my opinion, you have to have the experience of taking that version of the exam to be able to teach that certification. Things change version to version. No matter how many degrees you have. I had someone who had a Master's degree in Cybersecurity in one of my A+ classes, yet they had never set up antivirus before. I am 100% serious. Degrees and certifications are not equivalent. Just because you have a degree doesn't mean you can teach the material.
