@wes-bryan, It's true that you would be unable to teach us on every question variation that exists. That would definitely be an unrealistic expectation.
However, I do have an expectation that words and phrases that are on the flash cards and practice tests, that I paid extra for, should exist in the modules taught.
I chose this service in hopes that I don't have to start teaching myself. You say, "If you find a question that asks you a topic that you are unsure of, this is an opportunity to research that topic". I've gathered all the transcripts for mobile devices section into a single document, and then I searched for the word "push". Not a single time was the word push used. "pull" was found 4 times, but only in the Laptop Hardware and Components lesson that was not related to the term "pull synchronization".
Where am I supposed to research this? Outside of ITProTV? Because you certainly didn't teach it. If the expectation is that I pay you to teach me and then you tell me to go learn from someone else, then what am I paying you for?
The terms "pull synchronization" and "push synchronization" are terms that have direct explanations to them. They are just like battery term "memory effects" (which you did teach). If you did not say what memory effects are, then I wouldn't be able to know what that means. Thus the need for more information then was taught. The flash cards, you provided, are telling me phrases and concepts I wasn't taught. The flash cards also only give you the short answer and no depth of what Pull Synchronization is. So now have to go outside of ITProTV, but I shouldn't have to turn to the almighty Google when it's something that should have been taught.
I understand reaching out to different sources if you don't understand a way a person teaches. I got a little lost with Ports and Protocols, so I did go to other sources to try to find alternative ways of explaining ports and protocols. But that's because I knew that was my own shortcomings and after learning I revisited that lesson and was then able to understand.
However, if you were to have never mentioned the words ports or protocols in your lessons, and it showed up on the flash cards. The problem lays with you: the teacher.
I understand that you did not create these flash cards (I believe Kaplan did), but this just confirms that outside sources are giving me more information than this course.
If I wanted partial information, I would watch the free A+ videos on YouTube. Professor Messer offers the entire course for free. Because they are free, I cannot have the expectation to get me to certification status without potentially verifying their information and checking multiple sources. I didn't want that. So I went with ITProTV, but don't tell me that I need to do the same thing I could do for free, without you.
What are you going to do about the missing information that is not being taught?
