Answers:I prepared the test taking tips below for a school that I was assisting and thought that it might be helpful for you. The best way to be successful is to know your work because you have been conscientious in coming to class, paying attention, organizing your thoughts, coming to your own conclusions, doing your homework and asking questions if you do not understand something. There are a number of techniques which you can use to prepare for examinations. Some of these techniques are a way of breaking down, organizing your thoughts and seeing the relationships, and patterns that exist within subjects and even between various subjects. How Do I Use Critical Thinking Skills In Test Preparation And Answers A. It is important to be able to sort words and phrases and to classify them. This is done by having categories. Items are sorted into categories identifying the defining characteristics. The skill used is called classification. Topic to be classified: GOVERNMENTS Categories: Democracy Dictatorship Socialist Communist Monarchy Each category may be ( classified) further broken up into: How leader takes office How laws are made How laws are enforced Citizen rights and responsibilities How government services are paid for B. Go through past exams, class notes, and your textbook and compile a list of terms that are important for your subject. Place the terms in groups that YOU feel are similar. Understand the relationship of these terms which should be the reasons(s) why you placed them in the category of your choice. C. Many exams ask you to compare or to contrast two or more items. Sometimes they do not use this wording and ask for similarities or differences. This is particularly useful in History and English. In an English essay use the conclusion as your introduction and place and explain each similarity and difference in a separate paragraph as the body of the essay. Use the number of examples that are required in the essay. Your teacher maybe able to supply you with a form called a graphic organizer for this critical thinking skill. In doing this comparison you should have the following: How are they similar? How are they different? Place the differences in categories. What conclusion or interpretation is suggested by the significant similarities and differences? D. In Biology, Math and other subjects the skill Determining Parts Whole Relationship is particularly useful. You use this skill by having a whole object and listing each part, underneath each of the parts listed there should be a statement showing what would happen if that particular part was missing and then under that a statement of what is the function each part. The conclusion is the relationship between the parts and the whole.Your teacher may also have a graphic organizer for this skill. E Another skill that is very helpful in studying for the examinations is TAPPS. This is where you study with a friend.

In the following example if the choices are (A) big (B) blue (C) twelve (D) small the answer probably is A or D. M. If two answers are similar then one of the similar answers is probably correct. The choices are (A) Blue (B) Green (C) 25% (D) implied powers. The correct answer is probably A or B since they are similar based on the fact that they are both colors. N. Watch time
