Taking an ASVAB practice test is one of the best things you can do to prepare for the examination. There are a number of sources for comprehensive and realistic ASVAB simulations. It is a good idea to take an ASVAB practice test early on in your exam preparation. Often, people err by thinking they should wait to take a practice exam until they have studied all the exam content. They mistakenly believe the goal of a practice test is to score as high as possible. Of course, achieving a high score on an ASVAB practice test is a good thing, but the more important goal of taking the practice test is to diagnose those areas in which you need help.
By taking a practice test early in your preparation phase, you can avoid wasting time studying those areas in which you are already strong. Instead, you can focus your time and energy on deepening your understanding of subjects in which you are weaker. In other words, use an ASVAB practice test as a diagnostic rather than as a final evaluation. Besides using it to assess your knowledge of the various ASVAB content areas, you can also use a practice test to familiarize yourself with the time limitations. The ASVAB is designed to provide plenty of time to answer every question in every section. However, there will not be enough time for you to dawdle or linger excessively over difficult problems. Taking a timed ASVAB practice test is a great way to develop the right pace for the exam.
