1. Gaokao Exam in China

Administered by the People's Republic of China, the Nationwide Unified Examination for Admissions to General Universities and Colleges, also known as the Gaokao Exam (高考; "Higher Exam"), is the national entrance exam for higher education.

  • Eligibility: To get admission to higher education institutes (HEIs) in mainland China, final-year high school students must pass this exam.
  • Test Duration: This test lasts approximately 9 hours and for 2 days. Depending on the province, the number of days varies. In 2024, the exam is scheduled for June 7 and June 8.
  • Subjects: This most difficult test in the world includes Chinese, mathematics, and a foreign language (typically English). Students can select from several major subjects, including mathematics, science, history, and literature.
  • Success Rate: The Gaokao has a very low passing score. Fewer than 0.25% of applicants are accepted into China's most prestigious universities. For this reason, it is among the toughest yet popular tests to take in China.
  • Passing Score: Depending on the province and year, different scores are required to pass the Gaokao exam. Each province may have its own grading and scoring system.

Despite being the toughest exam in the world, the Gaokao is the most widely taken exam in the history of China, with 12.91 million candidates in 2023.
