Admission Requirements

• School and admission route: Halıcıoğlu Data Science Institute (HDSI). Data Science, including the joint Business Data Science major, is selective. Data Science is a selective (capacity-limited) major, so first-year applicants must choose it on the UC application and are selected for it through UC San Diego's holistic review and the number of places available. UC San Diego strongly recommends listing a non-selective alternate major on the UC application; if you are not admitted to your first-choice selective major you may be admitted to the alternate if space allows. Switching in later is hard: continuing students can apply once a year after finishing the screening courses with at least a C-, and places are awarded on a points system that also gives weight to California residency, first-generation status and Pell Grant eligibility
• Major restrictions: Data Science majors cannot double major or minor in any Computer Science and Engineering major, and CSE majors cannot double major or minor in data science
• Testing: test-blind. UC San Diego does not consider SAT or ACT scores in admission or scholarship decisions; if you send them, they may only be used as an alternative way to meet minimum requirements or for course placement after you enrol
• English proficiency (needed if your native language is not English and your secondary education was not taught in English): TOEFL iBT 4.5 on the scale used from January 2026 (83 for tests taken before January 2026), IELTS Academic 7 or Duolingo English Test 115. AP English Language or English Literature scores of 3-5, or IB English A scores of 5-7 at higher level or 6-7 at standard level, are also accepted
• Academic requirements: a secondary school completion certificate that admits you to university in your own country and is equivalent to a US high school diploma, plus UC's 15 'A-G' college-preparatory courses (2 years of history/social science, 4 of English, 3 of mathematics with 4 recommended, 2 of laboratory science with 3 recommended, 2 of a language other than English with 3 recommended, 1 of visual and performing arts and 1 elective). Non-California residents, including international applicants, need at least a 3.4 GPA in A-G courses taken in grades 10 and 11 with no grade below C, and competitive applicants are well above the minimums. You answer 4 of 8 Personal Insight Questions (up to 350 words each) and rank up to four of UC San Diego's eight undergraduate colleges, which set your general-education requirements
