Students in each class were randomly divided into two groups. One group was tested continuously during the semester but no tests were given to the group .At the end of the course, the scores of the two groups of students in each class as well as all the students regardless of the type class were compared under the same conditions. Results: Results demonstrated that in all four classes, mean scores in the students who were asked tested during the semester was significantly higher than the students who were not tested. This result was also true for all students, regardless of their field of study. From total of fifty four students who were questioned, only four students had a lower score toward other fifty four students.
