The choice to offer admission is based on the University of California's comprehensive review program, which considers a candidate's personal situation, community involvement, extracurricular activities, and academic potential in addition to the traditional high school academic record, personal statement, and entrance examination scores. While residency is not a factor in admission, it is a factor in tuition expenses, with out-of-state residents fees much greater than California residents. Since the approval of Proposition 209 in November 1996, California state law has prohibited all public universities (including UC Irvine) from practicing affirmative action as part of their admissions processes. Discoveries and innovation Machine Learning Repository The University of California Irvine hosts the UCI Machine Learning Repository, a data resource which is very popular among machine learning researchers and data mining practitioners. It was created in 1987 and contains almost 500 datasets from several domains including biology, medicine, physics, engineering, social sciences, games, and others. The datasets contained in the UC Irvine Machine Learning Repository have been used by thousands of students and researchers in the computer science community and facilitated the publication of approximately 26 thousand scientific articles. Student life Fraternities and sororities The first fraternities and sororities at UCI began in 1973 with three sororities (Delta Gamma, Pi Beta Phi, and Gamma Phi Beta) and three fraternities (Beta Theta Pi, Sigma Chi, and Phi Delta Theta). Major events and programs in the Greek Community include Songfest, All Greek Conference, Greek Week, BANG (Being a New Greek), and risk management programs (topics vary).
