Toughest colleges to crack worldwide

Which colleges around the world are the toughest to get into? like, taking into account acceptance rates, requirements, etc.

Sure, I'd be pleased to share some of the universities with the lowest acceptance rates and high entrance standards worldwide.

1. Stanford University, California, USA: With an acceptance rate of around 4%, Stanford is extremely selective. Applicants generally have top-notch grades, exceptional standardized test scores, and show outstanding personal qualities via essays and recommendations.

2. Harvard University, Massachusetts, USA: Another example of an ultra-competitive U.S-based institution, Harvard has an acceptance rate of around 4%. Besides superior academic statistics, Harvard particularly seeks students with unique talents and accomplishments, coming from diverse backgrounds.

3. Massachusetts Institute of Technology (MIT), Massachusetts, USA: MIT is one of the most selective colleges in the world, with an acceptance rate of under 7%. MIT seeks students who have demonstrated high achievement in rigorous academic courses and have a strong interest in STEM fields.

4. California Institute of Technology (Caltech), California, USA: Caltech, focusing on science and engineering, has an acceptance rate of around 6%. Besides academic excellence in the STEM fields, Caltech looks for students who have displayed significant extracurricular achievements.

5. University of Oxford, Oxford, UK: The University of Oxford is one of the hardest UK universities to gain admission to, with an acceptance rate of under 20%. Applicants must surpass high academic standards and outperform on the Oxford-specific tests and interviews.

6. University of Cambridge, Cambridge, UK: Cambridge has a similarly challenging admission process, with an acceptance rate of about 21%. Like Oxford, decisions are based on a combination of high school grades, admissions tests, and interviews.

7. Tsinghua University, Beijing, China: One of China's most prestigious colleges, Tsinghua University, has an acceptance rate of approximately 2% for Chinese nationals (though international student admissions are slightly higher).

Note these are just acceptance rates – all of these places have high standards and rigorous application processes, so they're indeed among the toughest to get into.
