Abstract
There are individual differences and characteristics in the growth of intelligence and intellectual capacity among students. These differences are reflected not only in terms of their various conditions of and capacities for learning, or their learning methods, but also in terms of the individual personal traits of the students and their identity with the "types" of learning. Therefore, studying the factors that influence the growth and development of students' intelligence and intellectual capacity holds a major significance for the task of improving the educational process and promoting the cultivation of talents for society's use. For the purpose of explaining the correlation between the various backgrounds of students and the development of their knowledge and mental capabilities, we will examine the test scores of the graduates of our medical institute from 1982 to 1984. During these years, these students sat for the general professional qualifying examination in comprehensive and clinical medicine. On the basis of these data, we attempt to draw some conclusions about the correlation between the various backgrounds of the students and the test scores they attained in the general examination. We will use these data to examine the factors that influence the development and growth of students' knowledge and intelligence.
