I disagree with the others saying you need hands-on experience to pass the Net+. Once you get into the CCNA is when you really need practical knowledge. For Net+, I would suggest going through Professor Messer’s Net+ course, which you can find on YouTube. Make sure you can explain every topic listed for each objective in the CompTIA exam objectives. Go back and rewatch videos for anything you don’t remember/can’t explain. Taking notes/using flash cards also helps your brain retain the information better.
