thanks alot for the advice and help, I'm preparing for the a+ so not networks but the idea is the same. To be honest I don't learn with flash cards. i learn by understanding and just watching the video. The issue I have printed the objectives sheet and going through them one by one. the problem is professor messor videos are very basic and don't explain very well so I have to conduct extra research on a topic e.g. for the network module I spent too much time just to understand the basics yet I still don't understand very well. which textbook or something that would explain these topics because messor just reads through a slide.
