Aptitude tests ( TOEFL , ACT , SAT , PSAT ), sometimes referred to as ability tests, require slightly different preparation. Unlike knowledge tests, aptitude tests measure potential and ask questions that go beyond a specific curriculum. The results help determine your natural strengths and weaknesses, and college guidance counselors often use them as a reference for academic direction. The best way to prepare for an aptitude test is to become familiar with the types of information covered and the types of questions that are asked. You could start by purchasing a study guide. It will cover every area of the test so you know what to expect, and many include information on time limits and the test’s scoring system. Also, take any practice tests available. Aptitude practice tests will allow you to get used to the types of questions asked, how they are worded and working against a time limit.
