Objective tests include such things as multiple choice, true/false, fill-in-the-blank, and matching. The following suggestions are primarily designed to help you with multiple choice and true/false questions. However, many of the tips found here will help with all types of questions. 

• Look for the main idea of the question. What is the author looking for? 
• Be on the lookout for key words like “none”, “never”, “always”, “except”, “most”, or “least”. When you see these words, circle them so that you remember how to best answer the question. 
• On multiple-choice tests, try to answer the question before looking at the answers. Then look at your choices and see if any of the answers match what you were thinking. 
• Don’t over-interpret test questions. Sometimes the obvious answer is just that! 
• If you are unsure of an answer on a multiple-choice item, eliminate as many wrong choices as you can. This improves your odds of getting the answer right. 
• Once you’ve made your selection, don’t change it unless you’re sure that the alternate response is correct. However, you may find it helpful to circle items that you are unsure of so that you can go back and double check your answer after you have completed the entire test. 
• On multiple-choice questions, cross off answers that are only partially correct, that you know are not correct, or do not answer the question. If you know one of the answers is not true, you can eliminate an “all of the above” choice as well. 
• Sometimes clues are available in other test questions. For instance, two questions on the same general topic, when read one right after the other, may give you information that will help you answer both. 
• Look for clues within multiple choice and fill-in-the-blank questions. For example, the verb tense (past, present, or future) and singular versus plural words should match between the question and the answer. 
• When you need to put your answer on a separate sheet of paper, such as scantron sheets for multiple choice tests, double check often that the number you are answering corresponds with the number you are filling in on the answer sheet. 
• Be careful with questions involving “all of the above” and “none of the above”. If you are sure that at least two of the choices are correct, then you may be safe in choosing “all of the above”. Likewise, if you are certain that at least one answer is correct, you can eliminate “none of the above”.
