Here are some additional tips that can help you become a Certified Network Defender: 

Have a Plan, Stick to a Schedule

An examination plan acts as a guide for your entire test prep journey. Before you get started hitting the books, you have to clearly outline your objectives and plan how you will accomplish them. Let’s be honest: any exam can be stressful, especially if it plays a major role in determining your career path. If you don’t have a reasonable guide set up, you run the risk of elevating this stress and wasting time on an unfocused study strategy. There are some critical aspects you have to cover while setting up your study plan.

The most essential one is the time: how long do you have to study before exam day? How much time can you spend studying each day? Do you prefer to study early in the morning before work, or in the evening after work is over? Answering these questions will be helpful when determining your study strategy. The next step is to divide up the content you need to study into different segments. Then you can allocate your limited time to reviewing each segment, ensuring that you don’t take too long on one particular area.

Find Your Study Strategy

What is the best methodology when preparing for the CND exam? Truthfully, there is no one-size-fits-all system that works for everybody. No two people learn the same way; what works for some probably won’t work for others. For example, some students learn exceptionally well through independent study, utilizing cheat sheets and practice questions. Others are more visual and learn best through video content such as recorded lectures. Still, others learn best in social gatherings such as a study group or live classroom environment. Comprehend your own qualities and shortcomings in order to determine your own form of intelligence.

Take Advantage of Practice Questions

CND exam questions are generally situation-based. These situations can vary wildly, which means that simply reading about certain concepts and strategies won’t necessarily prepare you for the exam. Fortunately, this is where test prep courses come in handy. Enrolling in a test prep course with a company like Grey Campus CND or Simplilearn can provide you with many practice questions to pull from, offering an accurate facsimile of the actual test environment. Furthermore, as you complete these practice questions and compare your results, you can see what areas of the exam are more challenging for you. This will inform your study process as you can then focus more effort on addressing these weak points in your networking knowledge.

Simulate the Real Thing

An expansion on the previous tip is to create your own simulated exam made from practice questions that are nearly identical to the actual exam. Even if you have an intimate working knowledge of all the material covered on the CND exam, it doesn’t necessarily mean you have the ability to pass it. You would do best to practice the act of taking the exam itself as well. The fact is that this test will require some stamina on your part since you will need to sit in the testing center for 4 hours and answer 200 questions to the best of your ability. If you organize an accurate simulation of the exam right down to the finer details of the testing environment, you can mentally and physically prepare yourself for success.

Don’t Get Nervous!

It doesn’t matter how much time you spend reviewing the material and how well you’ve prepared for the exam; stress comes for us all. It’s highly likely that you will experience pre-exam jitters that can negatively affect your test-taking ability. After all, the majority of us don’t perform well under strain; there are numerous factors that you can’t control. Remember to get a good night’s sleep, eat a nice breakfast, and use the restroom before your exam starts. Most of all: trust yourself and your knowledge of the exam material.
