Guessing - There is a penalty for a wrong answer, but it is still worth your while to make an educated guess. If you can eliminate answer choices that are obviously wrong, your odds of selecting the correct answer will be higher.
Follow you instincts - If you know the answer just by reading the question, youre probably correct. Look for the choice that is similar to your mental response and mark it on the answer sheet.
Look for obvious inconsistencies - A question may ask you for specific information, such as the number of feet in a specific distance. If any of the answer choices presents dimensions that are in degrees or seconds, youll be able to immediately rule it out.
