The recent scandal surrounding the NEET-UG exam in India drew international attention to the sheer scale of the exam, as well as the enormous pressure that the candidates are under. Such pressure that the sudden cancellation and stress of restudying led to tragic student suicides, and over 270,00 candidates, out of a registered 2.2 million, dropping out of re-sitting the exam. Not to mention the deep public anger and youth-led protests that eventually resulted in the resignation of the Education minister.
But this is not the only highly pressurised exam that takes place at vast scale in the world. For example, none even comes close in scale to China’s Gaokao, which involves 13.4 million candidates. For two days every June, the entire Chinese nation effectively hits pause. Construction work halts near exam centres, traffic is rerouted by police, and ambulances are on standby to treat panic attacks. The Gaokao is widely viewed as the ultimate equalizer—a single score that dictates a teenager’s economic destiny, university placement, and family honour in a hyper-competitive society.
Similarly, South Korea’s Suneung (the College Scholastic Ability Test) commands absolute national deference despite a smaller pool of roughly 500,000 candidates. On exam day, stock markets open late to keep roads clear for students, and the country’s airspace is completely grounded during the English listening section to prevent noise disruption. For South Korean youth, the Suneung is a brutal gateway to the elite “SKY” universities (Seoul National, Korea, and Yonsei).
The Two Types of Academic Torture: Scale vs. Depth
When evaluating the world’s most difficult exams, they generally fall into two categories: those that crush you with statistical scarcity (scale), and those that break you with conceptual complexity (depth). Exams like India’s NEET-UG or China’s Gaokao are brutal because of the sheer numbers. NEET-UG requires students to answer 180 questions in just over three hours. It is less about solving impossible equations and more about flawless, rapid-fire memorisation. Because a single incorrect bubble on an answer sheet can drop a student’s national rank by tens of thousands, the margin for human error is close to zero.
Conversely, exams like India’s JEE Advanced (for entry into the elite Indian Institutes of Technology) or the Master Sommelier Diploma Exam test the absolute outer limits of human capability. The JEE Advanced filters the top 250,000 students from a massive pool of over a million applicants. It does not care about speed; it cares about profound conceptual depth. The physics, chemistry, and mathematics questions frequently require students to combine multiple advanced theories just to solve a single problem—tasks that global academics note are tougher than standard undergraduate-level university work.
On the non-academic side, the Master Sommelier exam in Europe is a legendary test of sensory memory. It holds an estimated 1% pass rate. Candidates must look at, smell, and taste six completely unlabelled glasses of wine and within 25 minutes correctly identify the exact grape variety, country of origin, region, and vintage year. Many candidates spend decades, and thousands of pounds, failing it repeatedly.
The Cost of the Gatekeeper Culture
What connects all of these gruelling assessments is their role as societal gatekeepers. In regions with dense populations or severe economic competition, a single national exam is often viewed as the only fair, corruption-resistant way to distribute scarce resources —whether that resource is a coveted government medical seat, an IIT engineering badge, or a corporate fast-track ticket in Beijing or Seoul.
However, as the recent Indian NEET-UG leak and subsequent protests showed, relying entirely on a single-day, high-stakes testing framework creates a highly fragile system. When the integrity of that single day fails, the psychological toll on millions of young people is catastrophic. As the new academic year begins to get underway in many countries, the world’s most difficult exams remain stark reminders of the hyper-competitive reality that exists for many students.
