Obtain important information about the test you will be taking. Find out how long it is, how many questions there will be and what medium it will be administered through. Knowing exactly what to expect can help you prepare mentally and enable you to avoid surprise or confusion during the test.
Find and complete practice tests related to the test you will be taking. For instance, if you are required to complete an aptitude test for employment purposes, use career-related practice tests. 3 Smart Cubes and Psychometric Success offer a variety of sample tests, and Accredited Online Colleges offers links to a wide selection of tests. Focus only on questions that you can expect to see on the actual test. Aptitude tests are often timed, so practice using a timer. This will give you a much more concrete understanding of what to expect.
Focus on stress and anxiety reduction in the period leading up to the test. Stress can negatively affect your mood, sleep patterns, and ability to concentrate. This can have a negative affect on your performance during the test. Preparing for the test can help reduce stress, but additional relaxation techniques are advisable. According to Melissa Conrad Stöppler, MD, in "Stress Management," exercise, meditation and connecting with loved ones can help reduce your anxiety and therefore increase your ability to complete an aptitude test with confidence and focus.
When completing the test, answer questions you know first. If you are uncertain about a particular question, skip it. Once you have completed all of the other answers, go back and attempt the difficult questions again. If you spend too much time on a question you are uncertain about, you may be unable to complete all of the test and therefore may not be as successful.
Manage your time. Make sure you know how much time you have to complete the test, and use your time appropriately. Don't rush, as you might make mistakes. However, be aware of the remaining time and don't spend too much time on each question.
Read every question carefully. By giving each question your full attention, you will be less likely to make mistakes. Double-check all of your answers.
