Four Categories of Employment Tests.
The tests given to job applicants fall into four categories: General aptitude tests, practical tests, tests of physical agility, and medical examinations. You can practice for the first three. If the fourth is required, learn as soon as possible what the disqualifying conditions are, then have your physician examine you for them so that you do not spend years training for a job that you will not be allowed to hold.

To practice for a test, you must learn what the test is. Once again, you must know what job you want to apply for and for whom you want to work in order to find out what tests, if any, are required. Government agencies, which frequently rely on tests, will often provide a sample of the test they use. These samples can be helpful even if an employer uses a different test. Copies of standard government tests are usually available at the library.

Test Taking Tips.
If you practice beforehand, you'll be better prepared and less nervous on the day of the test. That will put you ahead of the competition. You will also improve your performance by following this advice:
  • Make a list of what you will need at the test center, including a pencil; check it before leaving the house.
  • Get a good night's sleep.
  • Be at the test center early--at least 15 minutes early.
  • Read the instructions carefully; make sure they do not differ from the samples you practiced with.
  • Generally, speed counts; do not linger over difficult questions.
  • Learn if guessing is penalized. Most tests are scored by counting up the right answers; guessing is all to the good. Some tests are scored by counting the right answers and deducting partial credit for wrong answers; blind guessing will lose you points--but if you can eliminate two wrong choices, a guess might still pay off.
