Consider the remaining choices and select the one you think is the answer.
At this point, you may want to quickly scan the Table 2 lists strategies for answering one-best- stem to be sure you understand the question and your answer. Select the appropriate answer.
Even if you do not know the answer, you should at least guess. Your score is based on the number of correct answers, so do not skip any questions. TABLE 2.
The actual examination is timed for an average of 50 seconds per question.
Remember that the lettered choices are followed by the num- bered questions. Consider covering this section first in the beginning of the test, These questions are usually accompanied by the fol- youll likely be less rushed and thus the probability of answer- lowing general directions. For each numbered item, select the appropriate lettered option.
We encourage you to use this section as more realistic to take the Practice Test after you have a basis for further study and understanding. This If you choose the correct answer to a question, will probably give you a more realistic type of test- you can then read the explanation: a for reinforce- ing situation, because very few of us sit down to a ment; and b to add to your knowledge about the test without study.
In this case, you will have done subject matter.
