You should remember a three-word strategy to studying for and passing the Network+: Divide and conquer.
You need to be smart about what you put effort into understanding and memorizing. Look at the Exam Objectives. If you scroll all the way to the bottom of the Exam Objectives, you'll see there is a list of hundreds of terms and acronyms. I would not encourage anyone to try and memorize every single acronym on that list. Instead, you should focus on WHATEVER is an OBJECTIVE. Here is a list of SOME of the things I would encourage you to memorize.
Leased lines
Copper Connectors
Fiber Connectors
Tools
Topologies
IPv4 Classes
Attacks
Troubleshooting Methodology
Command Line Tools
Troubleshooting Tools
OSI Model
Wireless Standards
Ethernet Standards
Wiring Standards
Standard Business Documents
Ports & Protocols
Look up everything I've listed above (and a lot of other things I missed out too that are listed on the Exam Objectives) and learn about them through different means (books, videos, podcasts, apps, etc) Don't just memorize something. Understand it. Understanding it will help you memorize it.
You should have a plan on how you plan on studying. Don't just study aimlessly. The Network+ exam is a marathon. People don't just get up one day and run a marathon. They train for it. The finish line is passing the exam, the race track is the Exam Objectives. Not everyone can successfully finish a marathon. You need to train (study) and condition (practice) yourself to be prepared to run and finish that race.
Remember to take it one day at a time. You should pay for and schedule the exam so that you have a set date for the exam which will incentive you to study instead of procrastinating. Take it one day at a time BUT HAVE A PLAN. DIVIDE AND CONQUER. BREAK THINGS UP INTO SMALLER MANAGEABLE CHUNKS. MAKE LISTS. BEFORE YOU ATTEMPT MEMORIZING SOMETHING, CHECK THE EXAM OBJECTIVES TO SEE IF IT IS WORTH YOUR TIME AND EFFORT TO MEMORIZE SAID THING.
