AFCAT EKT Preparation Tips

The AFCAT EKT is not a difficult exam and all that is required is a thorough understanding of the fundamentals. When studying for the AFCAT EKT, make sure you only use reliable study materials from authorized & recognized sources. Candidates are advised to follow the below AFCAT EKT preparation tips:

  • Study Wisely: While studying, take short notes and make a formulae list to help you revise for the AFCAT EKT. This will definitely help you remember everything you’ve learned. It’s not about how many hours you put in; it’s about how to make the most of those hours.
  • Practice Mock Tests: Practice as much as you can to become accustomed to a wide range of questions. Taking different mock tests will help you scale up your exam preparation, become aware of current trends, and improve your time management.
  • Manage Your Speed: The most significant element in any competitive examination is speed. Because EKT is a lengthy exam, you must increase your speed and ensure that you finish the paper within the time limit. Solve the questions you’re certain about first, then move on to the more difficult ones. This will greatly improve your time management skills.
  • Revise Topic-wise: For the Engineer Knowledge Test, you do not need to start from scratch. All you have to do is go over the topics you already know about again. Revisit the syllabus and proceed topic by topic. It will assist your mind in remembering things in a logical order.
  • Learn Important Formulas: The EKT syllabus is extensive as it covers everything the applicant learned while pursuing his/her engineering degree. Prior to the exam, you must make a list of all the important formulas and memorize them. It will assist you in saving time during the exam. You can highlight them in your book or make a separate list of them.
  • Solve Previous Papers: We’ve all heard that practice makes perfect. You must put what you have learned over the years into practice here. We recommend that you solve previous papers or model test papers that are available on the Internet. This will allow you to better gauge your level of preparation as well as plan your AFCAT EKT exam preparation.
