@Jordan-Donelson,
We cover each and every exam objective to the level of detail I believe you would need.
Having said that, it doesn't mean that simply watching a video is enough. If there is any topic that you do not understand fully after covering it, it means you do not understand that objective well enough to sit for the exam. You will have to study each concept until you are confident you know that objective at the verb level described in the exam objectives.
The CCNA exam is notoriously difficult to pass because of the single pass you have at the exam. Also, the timing, give yourself about 1 minute per question...any more than that you're at risk of failing...this means you must read the question, understand what they're asking you and know the answer and mark it confidently before proceeding to the next question.
So, though I can cover the material I believe is relevant for what will appear on the exam. I cannot insure that you have the background knowledge to set the context for each question or other skills in networking you should know before you you sit for this exam. If you're new to IT, this is not an entry level certification you should seek. If you don't have the equivalent of CompTIA A+ and Network+ level knowledge (not the certification) I wouldn't make this one your first certification.
All of the above is my opinion and experience in helping thousands succeed on their CCNA exam.
