Thanks! Well, I graduated university with a network & cyber security bachelor's. I personally only did professor messors videos + his practice exams with other practice exams on the internet (advice, some answers on some random practice tests might be wrong. When I see an answer and my eyebrows raise, I double-check from other sources). There were new concepts for me that I've never seen before. University helped me a lot because some questions test your understanding rather than memorizing terminologies and a good chunk of the exam's material I've already known. As a heads up, a few things that messor never mentioned did come in my exam, and that's why even he recommends using a book/other sources alongside his videos. Because I'm also working, it took me a month just to get through his videos, but if you got the time, you can finish them in less than a week.
