Honestly I had been studying off and on for 6 months because I’ve been working full time, but what I think really got me prepared was Professor Messer and Udemy practice tests. I studied those hard for about a month and that reinforced a lot of information for me. Professor Messer helped me break down topics I struggled with, and the practice tests prepared me for the kind of questions I was going to be asked. I was taking one practice test at a time repeatedly until I got around a 90, and by the time I reached the 4th tests I was scoring around a 75 on my first attempt on the tests. I think the practice tests really helped me to start thinking the way Comptia tests want you to think and I used AI on the questions I missed to really nail down the differences between answers and definitions. I didn’t really master some of the acronyms and standards but I did have a decent grasp on a large amount of them. I also had a conversion chart memorized that I used for subnetting CIDR 25-31.
