It's common knowledge that everyone studies differently. What may work for some may not work for others, but understanding how others study can greatly benefit how you approach studying yourself.
I think we should all take this opportunity to post methods and ways in which we study and prepare to take these tests.
Here's my contribution. Make flash cards to learn IOS. IOS is a command line operating system that has its own syntax and structure, and the only way to learn it is to drill it. I see people recommend to others to practice using the commands on an actual router or switch, but I've found that to be a very time consuming and ineffective method. Rather than actually typing the IOS commands, use your mind to visualize them by quizzing yourself with note cards. Write what the command does on one side, then write what the command is on the other. Read what the command does, then in your head visualize what the command is. If you use your mind, there's no question mark to ****, and no context clues either. In your brain, you can't hit the tab key to complete a command, you just have to know it. If you can clear the hurdle of learning IOS, it really makes learning the rest of the ideas and concepts much easier.
Please share how you guys study. Lets not argue about each others' study methods, because what works for one person may not work for another. This can be a great way to pick up ideas that can help you, so lets keep it civil and productive
