Six plans were prepared for each group, an achievement test consisting (18) sections was prepared, (7) sections of the true or false question type, (5) sections of the multiple-choice questions and (6) sections of the essay question. Face and Content Validity was discovered, the test reliability was found in the form of test -retest by conducting it on an exploratory sample consisting of (54) students excluding the students of the research sample they were tested again two weeks later, by using Person’s coefficient it was found to be (0.94), difficulty coefficient, discriminating power and effectiveness of distraction was found for multiple choice type questions.
