Cisco Certified Network Administrator, CCNA Part 1 - LCC101 Reviews

I am frankly scared and anxious for any real world work in this field. I feel like I just got a crash course in CISCO and only have more of a headache than I ever thought imaginable. I have no confidence in my ability to take and pass the real CCNA certification exam. I don't understand the vernacular. This course was like trying to take someone who's spoken English their whole life and try to teach them Spanish within a 2 week time period. Many students did not feel comfortable asking questions to the instructor - we felt it wasn't very approachable. I personally felt I was just slowing down the class and was the only person who didn't "get it" meanwhile several students reached out to me individually to mention they felt the same way. I think ACI learning needs to rethink this course. I am honestly disappointed and scared for my future. I have no clue what any of this means, why it's important, and how I will benefit from knowing any of this. Half the class was pointless labs, I feel. Just following instructions on a lab, sure I get "hands on" but it's not real. It doesn't make any sense. I feel bad for not understanding this stuff. Am I stupid? Or is there anything the instructor or ACI learning could have done differently or better? I imagine the truth is some combination of the two or it's somewhere in the middle as it always is.
