10 Toughest Exams In The World: Some exams in the world are so difficult that very few people can pass them. These are not just tests of knowledge but also perseverance, concentration and sustained diligence. These tests, which range from India's UPSC and JEE Advanced to China's Gaoka, are used to determine who is admitted to the top universities or most influential government positions. They have very high competition, lengthy syllabuses and challenging questions.
The Gaokao exam in China is reportedly even more difficult than the UPSC due to its rigorous structure, time constraints and high standards. Exams like the CFA and GRE are also well-known throughout the world for testing advanced academic or financial skills. While CCIE and GATE concentrate on engineering and technology, Mensa tests assess raw intelligence. The Master's Sommelier Exam assesses expert-level wine knowledge under pressure, and Oxford's All Souls Fellowship tests creative thinking.
