Which are the top 10 toughest exams in the world in 2025?
Every year, more than 2.5 million people across the world appear for some of the hardest exams in fields like government jobs, law, medicine, engineering, and business. These exams are tough not just because of the wide syllabus but also due to the very low pass rates.
The UPSC exam in India has a success rate of only 0.1 percent. In China, only about 1 in 6 students who take the Gaokao get into top colleges. Some exams like the CFA take years to complete and have a pass rate of just 22 percent in the first level.
These exams need months or even years of study, strong focus, and the ability to handle pressure.
The table below lists the top 10 Toughest Exams in the World:
What makes these exams stand out is not just the large syllabus, but how few people pass. Whether it’s cracking UPSC or clearing the CFA levels, they all need deep subject knowledge, years of study, and strong mental focus.
Which country has the toughest education system in the world?
Several countries have extremely challenging education systems, but three stand out: China, South Korea, and India. These systems are tough because of high student pressure, long study hours, difficult entrance exams, and low acceptance rates at top institutions.
Here's a quick comparison of how competitive they are:
These countries make students go through intense academic pressure from school itself. Success is seen as the only option, and failure often comes with social or financial consequences. The systems are not just about intelligence, but about mental stamina and years of preparation.
What makes China’s education system so competitive?
China’s system is built around the Gaokao, a 2-day national exam that decides if and where a student can go to college. It's often called the toughest high school exam in the world.
Reasons why it’s so demanding:
Gaokao is a make-or-break exam: It can decide your entire future. There's no second attempt within the same year.
12+ hour study days: Students often start preparing from middle school.
Extreme competition: With over 12 million students applying, only the top 0.1–2% get into elite universities like Tsinghua or Peking.
Limited spots at top universities: The demand is much higher than the supply, especially for Tier-1 colleges.
Parents also invest heavily in tutoring and coaching. Students face both school and family pressure, making the system even more stressful.
Why is South Korea known for intense student pressure?
South Korea’s education system centers around the Suneung, a standardized college entrance test taken once a year.
Here’s what makes it intense:
High-stakes test: A single test score decides university admission, job prospects, and even marriage potential in some cases
Long school + after-school hours: Students attend regular school and then hagwons (private academies) until late night.
Social pressure: Success is tied to family honor and social status. SKY universities (Seoul National, Korea, and Yonsei) are seen as the only path to a good life.
Mental health issues: South Korea has one of the highest youth suicide rates among developed countries, often linked to academic stress.
This culture of high achievement makes students feel constantly under pressure, with very little time for breaks or hobbies.
Is India’s competitive exam culture the most challenging?
India’s exam system is one of the most competitive in the world, not just because of population, but due to the sheer number of entrance exams and the difficulty of cracking them.
JEE Advanced (IITs): ~1.9 million (for prelims), <2% selected
UPSC Civil Services: ~1 million applicants, ~0.2% success rate
Limited seats at top institutes: Only a few thousand spots for IITs, AIIMS, or civil services.
Heavy dependence on coaching: Most students attend expensive coaching centers from early high school.
Years of preparation: Students often dedicate 2–4 years for a single exam.
India’s system values memorization, speed, and accuracy under pressure. It’s not just an academic challenge, but it’s a mental and emotional one too.
Which is the hardest university entrance exam in the world?
There are many tough university entrance exams around the world, but a few stand out for how intense and competitive they are. These exams not only test academic knowledge but also push students to their mental and emotional limits.
Below is a comparison of some of the hardest entrance exams globally:
Do Oxford and Cambridge interview rounds test IQ or mindset?
Oxford and Cambridge aren’t just checking how smart you are. They want to see the way you think. Their interviews focus on:
Problem-solving – Can you think through tricky questions undoubtedly?
Curiosity – Do you care about the subject? Do you ask good follow-up questions?
Understanding – Do you know the topic well, or just memorize facts?
Staying calm – Can you handle tough questions without getting flustered?
It’s not about having all the answers. It’s about how you learn, how you think out loud, and how open you are to new ideas.
What are the most difficult government exams globally?
Some government exams are known to be extremely hard, mainly because of how few people get selected, the vast syllabus, and the intense competition. These tests aren’t just about book knowledge. They also check your personality, problem-solving, and mental toughness.
For example, India’s UPSC Civil Services Exam has a success rate of less than 0.2%. The US Foreign Service Officer Test (FSOT) sees only a small fraction of applicants move past the first stage. In France, fewer than 5% of candidates crack the highly selective École Normale Supérieure entrance exam.
Here’s a comparison of some of the most difficult government or public service exams around the world:
Exam
Country
UPSC Civil Services Exam
India
Foreign Service Officer Test (FSOT)
USA
École Normale Supérieure Entrance Exam
France
CSS Exam (Central Superior Services)
Pakistan
Gaokao (for top government roles)
China
Administrative Service Exam (ENA)
France
These exams often take years of preparation, and success means access to some of the most respected jobs in the public sector.
What makes France’s École Normale Supérieure entrance tough?
The entrance exam to ENS (École Normale Supérieure) is one of the most elite and demanding in Europe. It's not just an exam, it's an entire selection process:
Long preparation: Many students study in specialized “classes préparatoires” for 2–3 years before even taking the exam.
Multiple written and oral tests: Subjects like literature, physics, or philosophy are tested at a level similar to final-year college courses.
Selective process: Out of thousands who apply, only around 200 get selected each year across all programs.
What makes it really tough is the depth. It’s not about memorizing; it’s about being able to think, argue, and explain complex ideas clearly and logically, often under pressure.
How demanding is the Foreign Service Officer Test (FSOT) in the USA?
The FSOT is the first step to becoming a US Foreign Service Officer, a job that involves working in American embassies worldwide. It’s one of the most selective government exams in the US.
Covers a wide range: The FSOT includes topics like US history, economics, world affairs, English expression, and even basic math.
Situational judgment test: You’re given real-world diplomacy problems and asked how you’d handle them.
Personal narrative round: After clearing the test, candidates must submit personal stories that show their skills and values.
Oral assessment: The final round involves group tasks, interviews, and case studies.
Only a small number of applicants make it through all the stages each year.
Which is the toughest exam for aspiring engineers?
Engineering entrance exams are known to be tough across the world, but some are far more competitive than others. From India’s JEE Advanced, which filters out only the top 1–2% of candidates, to Russia’s Unified State Exam, where scores directly decide university placements, the pressure is real.
Some global tests also test strong math foundations, like the discontinuedSAT Subject Test in Math Level 2, which was often taken by students aiming for top universities.
