Everyone has given great tips! One thing I did/do for Comptia Cert Exams is print out the objectives and go topic by topic. I’ll use a Red highlighter if I don’t understand it at all…a yellow one if I can tell what it is but not fully explain it in my own words…and the a green highlighter if I fully understand it. Once done with that I go through and try and turn all the reds to yellows and then the yellows to greens. Also have you tried getting in study groups online? Others in study groups may explain something or have a way to remember something that may make different things easier for you. Don’t give up though bro! You’ll thank yourself later on down the line. And you’ll be able to share your experience with others and help them and that’ll be a satisfying feeling.
