This strategy ensures that you answer all the questions you know and gives you an opportunity to come back to difficult ones later.
Another useful strategy is to carefully read the exam questions and instructions. Sometimes, the wording of a question can be tricky, with multiple parts or subtle nuances. Ensure that you fully understand what the question is asking before selecting your answer. Pay attention to terms like “except” or “not” that can change the meaning of the question entirely. If the question includes multiple parts or scenarios, break it down into smaller components and answer each part methodically.
One of the most helpful strategies during the exam is to eliminate incorrect answers. In most multiple-choice questions, there will be one or two answers that are incorrect. By eliminating these, you increase your chances of selecting the correct answer from the remaining options. Even if you are unsure about the answer, narrowing down your choices gives you a higher likelihood of guessing correctly.
Finally, practice mindfulness and stress management techniques during the exam. While it’s natural to feel nervous before a big exam, maintaining a calm and focused mindset can significantly impact your performance. Take deep breaths when you feel anxious, and remind yourself that you’ve put in the work to prepare for the exam. Staying composed throughout the exam ensures that you can think clearly and make informed decisions.
The strategies outlined above help you navigate the exam efficiently and effectively, giving you the confidence to tackle even the most challenging questions. When combined with solid preparation, a strong study plan, and adequate practice, these exam-taking strategies set you up for success on the JN0-105 exam.
