Iranian National Undergraduate Entrance Exam is the most competitive one in Iran. All high school students who plan to enter university must take this exam. In this exam, Students are ranked and according to their rankings, they apply to a number of universities. Last year, University of Tehran invited the top 1000 students (out of the whole 260,000) to visit the university. Our ACM Student Chapter, as the IT and CE Scientific Association of the University, had a number of representatives present that day to talk about information technology and computer engineering majors for students. Two of our members had a public lecture in an amphitheater and six others talked to students during the ceremony.
