1. Engineering
Engineering isn’t just one subject, it’s a combination of maths, physics, technical drawing and problem solving rolled into one. Whether it’s mechanical, civil, electrical, or aerospace, engineering demands deep conceptual understanding and practical application.
What makes it challenging:
- Complex mathematical modelling and theories.
- Heavy lab sessions and project deadlines.
- Constant technological updates.
Popular destinations: USA, Germany, UK, Canada, Japan.
Student POV: Students often juggle a packed schedule. Assignments, internships and late night study groups are the norm. Many say the workload is intense but the payoff is worth it.
2. Medicine
Becoming a doctor is a long and mentally taxing journey. It involves memorising thousands of terms, diagnosing conditions and learning procedures, while dealing with real patients.
What makes it challenging:
- A minimum of 5–6 years of study (plus internships/residencies).
- Life-and-death responsibility.
- Frequent practical assessments.
Popular destinations: UK, Australia, India, USA, Ireland.
Student POV: Med students often speak of long nights at hospitals and little to no personal time. The emotional toll of dealing with patients adds another layer of stress.
3. Architecture
Architecture blends art, engineering and creativity. Students must not only design but also ensure structures are functional and meet strict safety standards.
What makes it challenging:
- Endless design submissions and critiques.
- Learning multiple software tools.
- Long hours building physical models.
Popular destinations: Italy, UK, USA, Netherlands, Germany.
Student POV: Students often work into the early hours, perfecting details or reworking models. Burnout is common. But the joy of seeing your creation come to life? Unmatched.
4. Law
Law is about mastering legal systems, frameworks and case studies. It involves reading hundreds of pages and being razor-sharp with logic and argument.
What makes it challenging:
- Intense reading load.
- Heavy memorisation and writing.
- Critical thinking and application.
Popular destinations: UK, USA, Singapore, Australia, Canada.
Student POV: Law students joke that their textbooks could kill a person if dropped from a height. Expect hours spent reading case law and crafting arguments.
5. Chartered Accountancy (CA)
CA is not a traditional university course, but one of the hardest professional qualifications globally. It’s financially and mentally demanding.
What makes it challenging:
- Low pass rates.
- Self-study for most parts.
- Rigid exam structure with limited attempts.
Popular destinations: India, UK, South Africa, Australia.
Student POV: Most CA aspirants experience at least one failed attempt. The mental pressure is high, and it requires strong discipline and consistency.
6. Pharmacy
Pharmacy isn’t just about dispensing medication. It’s about chemical reactions, drug interactions and patient safety. It’s both a science and healthcare field.
What makes it challenging:
- In-depth chemistry and biology.
- Clinical internships.
- Ethical and legal responsibilities.
Popular destinations: USA, UK, Canada, Australia.
Student POV: Students need to remember hundreds of drug names and understand their effects. Internships at hospitals and research labs demand patience and precision.
7. Mathematics
Pure mathematics deals with abstract theories, logic and problem solving that require intense focus and mental agility. There’s often no real-world example to rely on—just pure logic.
What makes it challenging:
- Deep theoretical concepts.
- High failure rates.
- Often solitary and mentally exhausting work.
Popular destinations: Russia, USA, UK, France.
Student POV: Some students love the challenge, but many drop out mid-course. Success often depends on natural aptitude and passion.
8. Philosophy
This course may not seem challenging at first, but understanding, interpreting and debating centuries of abstract thought is no easy feat. It’s about analysing everything—time, existence, logic.
What makes it challenging:
- Abstract theories.
- Need for deep critical thinking.
- Heavy reading and writing.
Popular destinations: UK, USA, Germany, France.
Student POV: Students often describe it as a mentally exhausting journey. The questions you ask have no simple answers, and that’s the whole point.
9. Fine Arts
Art isn’t just about drawing. Fine Arts involves deep creative thinking, criticism, art history and practical execution—all graded subjectively.
What makes it challenging:
- Creative burnout.
- Long hours creating portfolios.
- Subjective assessment – no clear right or wrong.
Popular destinations: France, Italy, USA, UK, Netherlands.
Student POV: Many underestimate how tiring it can be. Artists must learn to take critique and keep producing original work under pressure.
10. Psychology
Why it’s tough: Psychology is both theoretical and scientific. It demands understanding the human mind and behaviour while also requiring strong research and statistical skills.
What makes it challenging:
- Vast amount of case studies and theories.
- Clinical internships.
- Requires both science and empathy.
Popular destinations: USA, UK, Australia, Canada.
Student POV: Students often describe psychology as rewarding but emotionally intense. Understanding mental health means confronting hard truths about human behaviour.
Conclusion
What’s considered “tough” depends on your strengths. If you thrive on logic, maybe law or math will suit you. Love people and help others? Medicine or psychology might fit better. No matter which course you choose, remember—challenge builds character. If you stay consistent and passionate, no course is too hard to conquer.
Whether you’re aiming for the top universities abroad or navigating local academic hurdles, make sure to choose a course that challenges you—but also excites you.
