Ask most students to name the hardest university in the world to get into and you will hear Harvard, Stanford or MIT. Those schools admit somewhere around one applicant in twenty-five. That is brutal. It is also nowhere near the bottom.
The lowest admission odds on the planet belong to universities that most international students never consider, because the odds are set by national entrance exams rather than holistic applications. A single exam, one sitting a year, millions of takers, a few thousand seats. Below them sit a handful of individual programs in London, Paris, Abu Dhabi and São Paulo where the applicant-per-place ratio quietly beats anything in the Ivy League.
We pulled every figure below from an official source: the university itself, the national exam authority, or the government body that allocates seats. Where a claim rests on anything less, we say so. And for each one, we answer the question that matters to you: if you are applying from abroad, do you face the same odds, or a different door entirely?
1. Peking University, Beijing, China: about 0.03 percent
China's gaokao is the largest exam on earth. The Ministry of Education counted 13.35 million registrations in 2025 and 12.9 million in 2026. Against that pool, Peking University admitted about 4,000 mainland students in 2025: 3,118 to its main campus and 900 to its medical campus, according to figures the university released. That works out to roughly 0.03 percent of gaokao takers, and about 0.02 percent for the main campus alone.
Your odds are also fixed before you sit down. Peking's admissions charter sets a quota for every province, published by each provincial authority, and admits by score from the top down within that quota. A student registered in a populous province like Henan is competing for a few dozen seats against more than a million takers. Third-party tallies put Henan's odds at one or two hundredths of a percent; Peking does not publish the by-province admit counts itself.
If you apply from abroad, none of this applies. International students go through a separate track: a foreign passport, an application window from January 1 to February 28, a written test in Chinese, English and maths in March, then an interview in April. There is also a test-free track based on standardized scores. Peking does not publish how many international applicants it takes, so there is no acceptance rate to quote, but the gaokao arithmetic is not your problem. Scholarships include the Chinese Government Scholarship, the Beijing Government Scholarship and Peking's own award for international students.
2. Tsinghua University, Beijing, China: about 0.03 percent
Tsinghua's numbers look almost identical, and the university publishes them cleanly. Its 2026 intake announcement lists just over 4,000 freshmen: about 3,800 from mainland China, 80-odd from Hong Kong, Macao and Taiwan, and 300-plus international students from 45 countries. Against 12.9 million gaokao takers, that is 0.029 percent.
One nuance the carousel version of this list got wrong: the gaokao score alone does not decide everyone's fate. Nearly 900 of Tsinghua's 3,800 mainland places, about a quarter, come through the "strong foundation" plan, which adds Tsinghua's own assessment on top of the exam, and several hundred more come through rural and special plans. The gaokao is held once a year, in early June, so a bad day means waiting twelve months to try again.
Yongsheng from Changchun wrote about the road from China's automotive capital to Tsinghua's automotive engineering program, which is the domestic version of this story.
If you apply from abroad, Tsinghua runs an online application and review with no gaokao: document screening, then a comprehensive assessment, with two application rounds between late September and the end of February. Tuition is 30,000 RMB a year for science and engineering, 26,000 for economics, management and law, and 40,000 for the arts, roughly $3,600 to $5,600. The Chinese Government Scholarship and Tsinghua's own scholarships are open to international freshmen.
3. IIT Bombay, Computer Science, Mumbai, India: about 900 sitters per seat
India's IIT entrance runs as a funnel. About 1.5 million students sit JEE Main. The top slice earns the right to sit JEE Advanced, and in 2026 the official results release shows 179,694 candidates appeared and 56,880 qualified. Those qualifiers are ranked, and rank decides everything.
The seat allocation body, JoSAA, lists 2,183 Computer Science seats across all 23 IITs for 2026, and 199 at IIT Bombay, the most sought-after department in the country. Measured against everyone who sat JEE Advanced, that is more than 80 sitters for every IIT Computer Science seat and about 900 for every seat at IIT Bombay. In the 2026 allocation, the open-category seats at IIT Bombay Computer Science closed at all-India rank 67. Sixty-seven, out of 180,000.
If you apply from abroad, the rules are different and, on paper, easier. Foreign nationals skip JEE Main and register directly for JEE Advanced, and their seats are supernumerary, capped at 10 percent per course and outside the reservation system. Very few take that route: only 147 foreign nationals registered in 2026 and 10 qualified. The catch is cost. IIT Bombay's 2026-27 fee schedule charges foreign nationals Rs 3,00,000 per semester in tuition, three times the rate for Indian nationals.
4. University of São Paulo, Medicine, Brazil: 1.1 percent
Brazil's best university is free, and the price of that is the vestibular. USP's entrance exam is run by Fuvest, which publishes the applicants-per-place ratio for every course. For the 2026 exam, 22,134 candidates registered for 244 places in Medicine: 90.7 candidates per place, or 1.1 percent. Psychology ran at 58.6 per place, International Relations at 37.9, and Law at 22.7. Across the whole exam, 111,480 candidates competed for 8,747 places.
The exam is two phases: an 80-question multiple-choice paper, then a written second phase with an essay and discipline questions. It is in Portuguese, and USP describes itself as public and free, so there is no tuition for anyone, Brazilian or not.
If you apply from abroad, you sit the same vestibular as everyone else, in Portuguese, with no separate quota. That makes USP Medicine one of the few entries on this list where an international applicant faces exactly the same odds as a local one.
5. École Normale Supérieure, Paris, France: about 1.5 percent
ENS is the strangest entry here, because you cannot apply to it from high school at all. The main route is two years of classes préparatoires after the baccalauréat, then a national concours. For the 2026 concours, ENS set the total at 192 places across all tracks: 72 in Arts, 25 in Arts and Social Sciences, 38 in Maths and Physics, and single or double digits in the rest. In the Maths and Physics track in 2025, the official concours service recorded 2,362 registered candidates for 35 places, about 1.5 percent. Successful French and EU candidates become salaried trainee civil servants with a ten-year service commitment.
École Polytechnique, France's other legendary grande école, works the same way: 5,780 prépa candidates for 399 places in 2025, or 6.9 percent, plus separate international tracks.
If you apply from abroad, ENS has a route built for you, but not straight from school. The International Selection takes students already enrolled at a foreign university, under 26, and admits about 10 in Arts and 10 in Sciences each year, with a selection rate ENS puts at 5 to 10 percent. Those admitted receive €1,000 a month for three years plus a campus room. Non-EU students may also sit the regular concours, but if admitted they enter as foreign students paying their own way rather than as salaried trainees.
6. Imperial College London, Economics, Finance and Data Science, UK: 2.6 percent
Imperial's statistics guide is one of the most transparent documents any UK university publishes. For 2023-24 entry, the Business School's undergraduate degree in Economics, Finance and Data Science drew 2,778 applications for 72 places: 38.6 applicants per place, or 2.6 percent. Computing, Imperial's flagship, took 202 students from 4,010 applications, 5 percent, and 61 percent of those applicants were from overseas. The course pages now quote 13 applicants per place for 2025, so the ratio has eased, but it remains among the tightest in the UK.
If you apply from abroad, it is the same UCAS form as everyone else, plus the TMUA test and an online interview for the economics degree. Overseas fees are steep: £45,500 a year for Computing and £42,700 for Economics, Finance and Data Science. Imperial Inspires Scholarships offer £15,000 a year to overseas students. Ashmita wrote about why she chose Imperial for biotechnology.
7. NYU Abu Dhabi, UAE: 2.9 percent
NYU Abu Dhabi is the one university on this list that runs a fully American-style holistic admissions process, and it still lands below every Ivy. In its own Class of 2029 profile, NYUAD reports a 2.9 percent admit rate, 485 enrolled students from more than 80 nationalities, and a 71 percent yield, meaning almost everyone who gets in says yes.
The reason both numbers are extreme is the same: money. Tuition is $68,574 for 2026-27, but financial aid is entirely need-based and open to every applicant regardless of citizenship, filed through the CSS Profile. Ania from Poland went from an IB school to a full ride there, and Borderless has 40 NYUAD stories in total, many of them full scholarships.
If you apply from abroad, there is no separate track. Everyone applies through the Common App, and finalists are flown in for a Candidate Weekend. Early Decision I closes November 1, Early Decision II January 1, Regular Decision January 5.
8. London School of Economics, Politics and International Relations, UK: 3 percent
LSE prints the applications-to-intake ratio on every course page, and the numbers for 2025 entry are startling. BSc Politics and International Relations took 33 students from 1,100 applications, a 33-to-1 ratio, or 3 percent. Philosophy, Politics and Economics ran at 24 to 1, Data Science at 24 to 1, Finance at 22 to 1, and even the flagship BSc Economics, with 2,885 applications for 217 places, at 13 to 1. These are intake figures, students who enrolled, so they understate the offer rate slightly and are still tighter than most Ivy League acceptance rates.
If you apply from abroad, it is one UCAS application, deadline January 13, 2027, and LSE does not split the ratio by nationality. Overseas fees for 2027/28 are £33,800 for Politics and International Relations and up to £41,900 for Economics, fixed for the length of the degree. LSE's scholarships for overseas undergraduates are awarded on need first, then merit. Khudadad, who studies Public Policy with Politics, wrote about the long road to an LSE offer.
9. University of Oxford, Economics and Management, UK: 5 percent
Oxford publishes a success rate on every course page, and Economics and Management sits at the bottom: 5 percent successful, 18 percent interviewed, an intake of 82, averaged over 2023 to 2025. The department's own report for the 2025-26 cycle shows 1,421 applicants, 280 shortlisted and 97 offers. Computer Science is at 7 percent, Medicine at 11, PPE at 12.
Here is the number that matters if you are reading this outside the UK. In the 2025-26 cycle, 724 of the 1,421 applicants were from outside the UK, and they received 31 of the 97 offers: a 4.3 percent offer rate, against 9.5 percent for UK applicants. And you get one shot: one course, one of Oxford or Cambridge, once a cycle, with the UCAS deadline on October 15.
If you apply from abroad, the route is identical to a UK applicant's: UCAS, an admissions test in October, and interviews in December. Overseas fees are £46,210 a year. Ameya from Bangalore got into Oxford Law with science-heavy A-levels and wrote a roadmap for applicants coming from a non-traditional background.
10. University of Cambridge, Computer Science, UK: 7.4 percent
Cambridge's 2025 admissions statistics show 1,739 applications for Computer Science, 163 offers and 128 acceptances: a 7.4 percent success rate, the lowest of any Cambridge course, and 13.6 applicants per place against a university-wide average of about six. Economics came in at 10 percent.
The same document has the number international applicants should read twice. Across all subjects, overseas applicants were accepted at 10.5 percent, against 19.6 percent for UK applicants. Cambridge does not publish that split by course, but there is no reason to think Computer Science is gentler.
If you apply from abroad, it is UCAS by October 15, an admissions test, and a college interview. International fees for 2026 entry are £44,214 a year for Computer Science plus a separate college fee. Arnold from Shanghai got into Chemical Engineering and Biotechnology and wrote about why the interview is the moment that decides it.
Start your own journey
A 3 percent acceptance rate is not a reason to skip a university. It is a reason to apply properly: the right test, the right deadline, the right story, and a college list that surrounds one long shot with places you can actually get into and afford.
Kai, the Borderless AI college counselor, builds that list with you. Tell Kai your grades, your budget and where you want to go, and it puts the reach schools on this page next to matches and safeties, turns every deadline into a task, and works through the essays, from the Oxford personal statement to the NYUAD Common App. It is free to use.
