Some degrees don’t just challenge you; they completely occupy your schedule. Passing them requires endless studying schedules and sometimes even sacrificing your sleep. They test your memory, understanding, and your ability to survive under pressure. Such courses are considered the toughest degrees in the world. 

Despite being one of the most challenging courses, people opt for it due to good career prospects. In this guide, we are ranking the top hardest degrees in the world based on study hours, dropout rates, GPA, admission requirements, and students’ mental health. This will also include how CounsellingX helps you secure admission to your desired subject and to the most suitable university.

How We Ranked These Degrees

We evaluated each degree across 4 different criteria. These included 

1. Study Loads: Weekly hours required, including labs, practicals, self-study, and clinical rotations.
2.  Dropout Rate: The number of students who enrolled for a particular course and failed/left in the middle.
3. Professional Exams: Difficulty and pass rate of board or licensing exams.
4. Career Prospects: Real-world implications of errors, burdens, and learning demands.

What are the hardest degree subjects?

Considering the extreme length and course requirements, Medicine (MBBS/MD) is considered the toughest subject in the world. The rest of the list consists of Medicine (MBBS/MD), Aerospace Engineering, Quantum Physics, Architecture, Chemical Engineering, Law, Neuroscience, Chartered Accountancy / Finance, Philosophy, and Computer Science.

Medicine (MBBS / MD / MBChB)

The Medicine course is no doubt one of the toughest degrees to pursue. Despite this, many students dream of pursuing a career because of the well-paying and respectable career prospects. In the United States, around 54,699 people applied to medical schools. This represented a  5.3% increase from 2024.

Medical students should study Human Anatomy, Physiology, Biochemistry, Pathology, Pharmacology, Microbiology, Internal Medicine, Surgery, Obstetrics, Gynaecology, Psychiatry, etc. 

The duration of this course is around 5 years in the UK, Australia and Pakistan, and 8 years in the United States, including pre-med, can span 8 years. The dropout rate is around 11.7% to 12.5%, and competition for admission is also high, especially at top global universities, where acceptance rates are relatively low.

• First-year students learn 10,000+ new medical terms at most accredited schools
• Clinical rotations bring 60 to 80-hour workweeks with real patient care responsibility
• USMLE Step 1 preparation requires 300 to 500 dedicated study hours
• After graduation: 3–7 year residency programs, often at 60 to 80 hours/week
• Neurosurgery training totals up to 16 years from high school graduation

Career Outcomes

Aerospace Engineering

I asked a friend of mine studying Aerospace Engineering how the second year feels like, and there was a distant look in his eyes. That is the year when you start studying fluid mechanics, thermodynamics, and advanced mathematics, all at the same time. The dropout rate is around 50%, and data from multiple universities support this.

An aerospace engineering degree combines physics, mathematics, materials science, and fluid dynamics and demands accuracy in all. A small calculation error in a real-life application means more than just a wrong answer on the test. It means a failed launch, a structural failure, and, in some cases, worse.

Engineers working on major space programs work under high-pressure environments where small trajectory errors can mean mission failure costing billions of dollars, so accuracy is a must. 

• An aerospace engineer must be proficient in MATLAB, ANSYS, OpenFOAM, and SolidWorks before the final year.
• Computational Fluid Dynamics (CFD) is widely considered the single hardest course
• A Professional Engineering License requires around 4 years of post-grad work experience.

• Stanford University (USA)
• California Institute of Technology (Caltech) (USA)
• Georgia Institute of Technology (USA)
• University of Michigan, Ann Arbour (USA)
• University of Cambridge & Imperial College London (UK)
• Delft University of Technology (TU Delft) (Netherlands)
• National University of Singapore (NUS) (Singapore)
• Nanyang Technological University (NTU) (Singapore)

Quantum Physics (Theoretical Physics)

This degree actually requires you to think beyond vision. It asks you to unlearn how you naturally think about the world. Consider particles that exist in multiple states simultaneously and learn about mathematical frameworks that have no physical equivalent. 

A strong understanding of this subject demands a strong Mathematics background. However, the hardest part isn’t Math, though it is difficult. It is actually failing to picture what you are learning and just blindly trusting the equations. The dropout rate is also high, and if the idea of studying a degree excites you rather than frustrates you. It's a good sign.

•  Schoridinger equations, Hilbert spaces and Dirac notations replace any intuitive model of the physical world itself.
• Most PhD-level physicists spend more than 10 years before reaching their desired specialised field 
• Career paths include quantum computing, particle physics research, academic science and quantitative finance.

• University of Cambridge (UK)
• Caltech (USA)

Architecture (B.Arch / M.Arch)

A 2019 study in the Journal of Architectural Education confirms that architectural students have the highest levels of sleep deprivation, averaging around 5.28 hours of sleep per night due to high academic demands. All-nighters in architecture schools aren’t just for exams; they are for normal Tuesdays as well.

It's actually hard to distinguish whether architecture is science or art. It is a blend of both, and to be a good architect, you need to be good at both.  Moreover, architecture school is mostly project-based, and grading depends less on exams and tests. Rather, it depends on your project’s markings. Their work is criticised publicly by professors and professionals in what’s called a ‘crit’.

So technically, architecture school takes up time. In a National Survey of Student Engagement study, architecture students devote more time to their degree than any other students.

• Students must master AutoCAD, Revit, SketchUp, Photoshop, InDesign, Enscape, Lumion, along with the theory and environmental physics.
• Full qualification takes around 8 to 10 years in total.
• Final thesis projects require over 2000 hours of work.

• UCL (University College London), The Bartlett (London, UK)
• MIT (Massachusetts Institute of Technology) (Cambridge, USA)
• Delft University of Technology (TU Delft) (Delft, Netherlands)
• ETH Zurich (Zurich, Switzerland)
• Harvard University (Cambridge, USA)
• Politecnico di Milano (Milan, Italy)

Chemical Engineering

If you have ever heard that Chemical Engineering combines every single science subject you have ever studied, that is not exaggerated. Physics, Chemistry, Mathematics, Biology, and Economics all contribute to the Chemical Engineering course.  

What makes Chemical Engineering particularly difficult is that it requires students to understand scientific principles and then apply them to large-scale industrial systems. One day, you are solving differential equations; the next, you are designing a process plant capable of producing thousands of tonnes of product every year.

• MIT (USA)
• Stanford University (USA)
• University of Cambridge & Oxford (UK)
• National University of Singapore (NUS)
• ETH Zurich (Switzerland)
• Tsinghua University (China)
• UC Berkeley (USA)                                      

Law (LLB/JD)

Law is hard in a completely different way from every other degree on this list. There's no calculus, no lab work, no coding. What there is is an almost incomprehensible volume of reading, a demand for linguistic accuracy that makes even small word choices important, and assessment criteria is also made as per that. You don't just answer questions in law school. You argue.

The Socratic method, which is still used at Harvard, Yale, Oxford, and Cambridge, means professors don't lecture at you. They cold-call you, ask you to defend a position, then ask you to defend the opposite position, in front of the whole room. 

• The Socratic method creates intellectual pressure from literally the first week of the first year
• Law GPA curves are typically set at a strict B/B+ median, top marks are intentionally kept scarce
• Corporate lawyers must understand derivatives accounting; patent lawyers must understand semiconductor physics; the law follows wherever business goes
• Post-graduation path: bar prep, bar exam, and often an LLM or judicial clerkship before top careers
