The study examines the relationship between social class and university entrance exams at the Bu-Ali Sina University of Hamedan, using Bourdieu's theory of cultural reproduction. We did a survey and employed a questionnaire. In addition, we used a stratified random sampling method and chose 370 students as a sample from the research population which consisted of 12500 students. Bivariate analyses showed that there was no meaningful relationship between social class, work ethic, hope, and food security and the rank of the entrance exam, but there was a meaningful relationship between social capital network, and IQ and the rank of entrance exam. The findings also demonstrated that there was a meaningful difference between IQ and performance in the examination in popular and less popular fields, i. e. the students of popular fields answered the IQ questions quickly. But both groups of students had no difference in hope. And there was no difference between social class and performance in popular and less popular fields. Furthermore, we found an inverse relationship between food security and IQ rate.
