1. UPSC Civil Services Examination
The Union Public Service Commission (UPSC) Civil Services Examination is one of India’s most competitive government recruitment examinations.
It consists of three stages: Preliminary Examination, Main Examination, and Personality Test.
Candidates must prepare subjects such as history, geography, economics, polity, current affairs, ethics, and essay writing. The extensive syllabus and limited vacancies make the selection process demanding.
Successful candidates may enter services such as the Indian Administrative Service (IAS), Indian Police Service (IPS), and Indian Foreign Service (IFS), subject to rank, preferences, and allocation rules.
2. IIT JEE Advanced
JEE Advanced is the entrance examination for admission to undergraduate programmes at the Indian Institutes of Technology (IITs).
The examination tests Physics, Chemistry, and Mathematics through challenging conceptual and numerical questions.
Its complex problems, strict time management, and competition for limited seats make it particularly demanding for engineering aspirants.
3. Gaokao
Gaokao is China’s national college entrance examination. It plays a major role in determining university admission for Chinese students.
The examination involves subjects such as Chinese, Mathematics, and foreign languages, along with additional subjects depending on the student’s selected pathway.
The high academic expectations and importance of examination results make Gaokao a significant challenge for students.
4. GATE
The Graduate Aptitude Test in Engineering (GATE) is conducted for postgraduate admissions and recruitment opportunities in technical fields.
It evaluates undergraduate-level knowledge in engineering, technology, science, and selected interdisciplinary subjects.
Candidates aiming for admission to institutions such as IITs and IISc or recruitment opportunities in certain public-sector organisations often prepare extensively for GATE.
5. NEET-UG
The National Eligibility-cum-Entrance Test (NEET-UG) is India’s principal entrance examination for undergraduate medical education.
It covers Physics, Chemistry, and Biology, including Botany and Zoology.
The extensive syllabus, accuracy requirements, and competition for medical seats make it challenging for students aspiring to study MBBS and other covered medical programmes.
6. USMLE
The United States Medical Licensing Examination (USMLE) is a professional examination pathway for medical licensure in the United States.
It assesses medical knowledge, clinical reasoning, and the ability to apply medical concepts to patient care.
Its multiple examination stages and extensive medical content make it demanding for medical graduates seeking to practise in the United States.
7. Chartered Financial Analyst (CFA) Exams
The CFA examinations are professional finance examinations administered by the CFA Institute.
The programme has three levels, covering topics such as investment analysis, financial reporting, portfolio management, economics, and ethics.
Candidates need sustained preparation and a strong understanding of financial concepts. Completing all three levels is an important step toward earning the CFA charter, subject to additional requirements.
8. Graduate Record Examination (GRE)
The GRE General Test is used by many graduate schools as part of their admissions process.
It assesses verbal reasoning, quantitative reasoning, and analytical writing skills.
Although the examination is not a professional licensing test, achieving competitive scores can be challenging for applicants targeting selective postgraduate programmes.
9. All Souls Prize Fellowship Examination
The All Souls Prize Fellowship Examination is associated with All Souls College at the University of Oxford.
It is known for its demanding essay-based questions and emphasis on independent thought, argumentation, and intellectual analysis.
The examination is intended for a highly specialised academic selection process rather than general university admission.
10. Mensa Admission Test
Mensa is an international organisation for people who meet its qualifying intelligence-test requirements.
Its admission tests assess reasoning and pattern recognition through standardised testing procedures.
The test is different from academic entrance examinations because it focuses on qualifying cognitive ability rather than a broad subject syllabus.
