Deciding on your degree is an important decision. Every university course has its own difficulties, but some are far more challenging due to a variety of reasons. This includes long placements for hands-on experience in Medicine, complex design challenges in Aerospace Engineering, or complex theoretical content in Veterinary Science.
This guide will explore the top 10 hardest degrees in the world and what makes them so challenging. Bear in mind that this list is our opinion, and there is no single hardest degree for every student. A course that is overwhelming for somebody may suit the abilities and interests of another.

What makes a hard degree?
Several features make the toughest courses stand out:
- Workload - Some degrees will expect long hours of study. This can include long lectures, extensive reading lists, and hours of private study.
- Subject matter - Courses like Mathematics and Physics are among the hardest because students need to understand abstract ideas and solve advanced problems, such as differential equations.
- Practical training - Students are also assessed by clinical placements in degrees like Medicine, Dentistry and Veterinary Medicine.
- Frequent assessment - There can be a variety of examinations, such as laboratory reports, essays, and major projects. This can create a feeling of constant pressure.
- Course lengths - Degrees like Medicine can take several years longer than most other courses. There may then be paid training after your degree has finished before becoming fully qualified.
- Emotional demands - You may find yourself in difficult or upsetting situations, such as caring for patients at a hospital or animals in a veterinary practice as part of a practical placement.
Our ranking takes into account these factors. The list is designed to show what you can expect, rather than discourage you from an ambitious course. It's also worth bearing in mind that the difficulty of a degree is subjective, as it depends on the qualities of the individual, such as their strengths and weaknesses, study habits, and interests.
List of the hardest degrees in the world 2026
1. Medicine
Medicine is considered one of the hardest degrees in the world. It normally lasts 5-6 years in the UK. When you graduate, you then take further paid training before being able to practice independently.
There is a vast amount of information to learn. This includes anatomy, disease, diagnosis, pharmacology topics for a potential career in pharmacy, and patient care. Students have to take clinical placements to assess them applying this knowledge to real-world healthcare.
The course can be emotionally tiring. Medical students will treat patients with illness and be distressed by difficult decisions in the course of their placements. It's important to display strong judgment, communication, and attention to detail.
If you need extra support, TeachTutti has experienced A-Level Chemistry tutors to advise you on preparing for a degree.
2. Veterinary medicine
Studying Veterinary medicine is similar to human medicine. However, there is an enormous amount of material to learn, as students need to understand the health and anatomy of several animal species.
As with Medicine, this degree includes lectures, laboratory work, and clinical placements. Students will learn diagnostic skills, how to perform surgery, and how to handle and treat animals. The animals won't be limited to pets and could include farm or zoo animals, each with different needs.
Students will come across upsetting situations when they treat ill animals and support concerned owners. Compassion and practical confidence are just as important as practical ability.
3. Aerospace engineering
As the name suggests, Aerospace engineering focuses on aircraft. This includes the design and development. The aircraft you will study include fixed-wing aeroplanes, rotary-wing helicopters, and unmanned aerial vehicles (UAVs). You need to understand advanced mathematics and physics, as well as aerodynamics, propulsion, materials and flight control.
Students will learn complex theories and how to apply them to design problems. There will be laboratory work, computer modelling, and group projects. The designs need to meet strict assessment standards for safety, weight, performance, and efficiency.
You need to be creative and precise, as a small mistake can affect an entire system. You'll need to understand how many separate components work together, and a strong foundation in maths is required.

4. Architecture
Architecture is creative and technical. You will create attractive designs that need to tick boxes for safety, materials, sustainability, and the needs of the people who will use the space, such as wheelchair accessibility.
There is an intense workload. Design projects typically take many hours. Models, drawings, and presentations must be to a high standard. You'll get detailed criticism for your work that you need to apply going forward.
Technical knowledge and time management are important attributes. You'll be working on several parts of a project at any one time. If you want to pursue this degree, follow the link to learn more with a qualified Architecture tutor.
5. Physics
Physics focuses on the rules that govern the world around us: matter, energy, space, and time. It is among the hardest degrees due to being highly abstract, and you'll encounter complex theories and mathematical models.
Students need a good grounding in calculus, algebra, and statistics. These skills are used to solve problems without an obvious answer. There is also laboratory work that requires careful measurement, data analysis, and reporting.
It's important to avoid gaps in your understanding, as each topic builds on what you are expected to know. It's a good fit for students who like difficult questions and finding their way through trial and error to possible answers. Consider learning with a DBS-checked A-Level Maths tutor to prepare for this degree.
6. Mathematics
If you enrol in a Mathematics degree, you'll explore abstract ideas, construct proofs, and learn why rules in maths work as they do.
There are several stages of logical reasoning for most questions. As well as answering, you need to give a clear argument for why it is correct. It can feel very different from studying at school, particularly in topics like real analysis, abstract algebra, and topology.
As mentioned with previous subjects, new topics rely on earlier knowledge. This means you need to address gaps in understanding quickly to avoid falling behind at an increasing rate. Students in Maths need to be patient, accurate, and willing to try different approaches to a problem.
7. Chemistry
You will combine theory with practical work in Chemistry. Students will explore the composition and behaviour of matter. They will also learn how chemical reactions happen.
Areas explored in this degree include organic, inorganic, and physical chemistry. There are complex ideas, reactions, and calculations for every topic. Expect to spend a lot of time in the laboratory, where you'll follow precise methods, handle materials safely, and record your findings.
When you've finished your lab work, you need to analyse your findings and write up detailed reports. If the result is unsuccessful for an experiment, you'll need to identify what went wrong. Learn with a testimonial-approved Chemistry A-Level tutor to brush up on the core principles.
8. Dentistry
Dentistry combines medical science with practical training. Students learn about anatomy, disease, materials, and patient care. They'll then apply this understanding in a clinical setting.
You need excellent hand control for a career in dentistry. The operating space is very small, and a minor error can have serious consequences. You must use specialist equipment securely while ensuring the patient is as comfortable as possible.
It is more academically demanding than some students expect. You need to remember lots of information, comparable to other science degrees, and make sound decisions under pressure. It can be emotionally draining due to the stress of treating patients in your clinical placement.
9. Law
There is a vast amount of detailed material to read and understand as a Law student. This includes legislation, legal principles, academic commentary, and judgments from earlier cases.
Students have to identify the problem in a case and form a convincing argument by referencing the relevant rules to the specific situation. Written answers must be clear and supported by evidence. Even a slight deviation in wording can affect the meaning of a legal point. For example, consider the complex, specific jargon in the terms and conditions for most companies.
As well as reading, students need to write essays and research cases. You also need to consider different viewpoints rather than settle for one simple answer. Strong reasoning and communication skills are a must.

10. Computer science
You need to have strong mathematical ability, technical creativity, and an abundance of logical thinking for a degree in Computer Science. Students learn how computers process information and how software is used to solve problems.
You'll be expected to program in a variety of languages, including Python and Java. The course may also cover algorithms, data structures, artificial intelligence, cybersecurity, and computer architecture. You'll need to understand the theory for these topics, as well as complete practical projects.
Fixing coding errors requires a lot of patience. A small mistake in logic or syntax can cause a program to fail, and the problem may not always be clear, even with debugging. Students will also have to adapt their understanding as the course progresses, with technology advancing so quickly.
Dropout rate
The figures below are from the Higher Education Statistics Agency's 2019-20 academic year. It's the latest HESA table to compare dropout figures by subject across the UK. The data measures the percentage of undergraduate students who have left higher education, rather than those who just left their original course.
| Degree in this list | HESA subject group | Non-continuation rate |
| Medicine | Medicine and dentistry | 1.4% |
| Veterinary Medicine | Veterinary science | 1.7% |
| Aerospace Engineering | Engineering and technology | 7.2% |
| Architecture | Architecture, building and planning | 7.2% |
| Physics | Physical sciences | 6.5% |
| Mathematics | Mathematical sciences | 5.0% |
| Chemistry | Physical sciences | 6.5% |
| Dentistry | Medicine and dentistry | 1.4% |
| Law | Law | 5.2% |
| Computer Science | Computer Science | 9.8% |
Computer science has the highest dropout rate. There is a much lower rate for Medicine, Dentistry, and Veterinary Science. This is despite the course difficulty, suggesting that degrees often considered challenging are not the only factor in whether a student continues their studies. Entry requirements, motivation, teaching quality, financial pressure, and support are all metrics that affect student retention.
Bear in mind that the figures are for broad subject groups, rather than a specific course, like Aerospace Engineering. For example, Medicine and Dentistry have the shared category of "Medicine". The current Office for Students data is more recent, but uses different coverage and is less relevant than the UK-wide data above.
Preparing for one of the hardest degrees
Preparing for a demanding degree can make the transition smoother. Start by looking at the entry requirements for the universities you're looking at. The same course may have different subjects, grades, or admissions tests depending on the institution. Knowing this can help you pick your A-Levels and extra-curricular activities if needed.
Try to understand concepts rather than relying on rote memorisation. Gaps in your knowledge can be a particular issue in subjects like Maths and Chemistry, where earlier topics are built upon in greater detail. If there is a strong essay-writing element, you will need to show clear analysis and structured arguments. TeachTutti has qualified A Level English Literature tutors to help develop reading and writing skills.
Try to learn as much as you can about the course. Go to open days, compare modules, and speak to current students. Look at the balance between lectures, exams, projects and placements. Is there a shift in focus or assessment after year one? Knowing these details will help you understand whether the degree is a good fit.
Choosing the right degree
Avoid choosing a degree based on the reputation of the course or the university you will attend. The degree that is suited to you will play to your interests, strengths, and any long-term plan.
Take a look at the work you will need to complete. Chemistry favours students who enjoy practical experiments, while Maths or Computer Science will reward those who enjoy logical problems. If you like reading and structured arguments, Law is a good choice.
Courses will be taught and assessed in different ways. There is further variation depending on the university: some may emphasise final exams, while others may assess you through projects, essays, or practical work. What format plays to your abilities?
Ultimately, if you enjoy a course, you will stay committed when the workload increases and the academic difficulty ramps up. Career options and salary matter, provided that you can stay motivated.
Conclusion - Top 10 hardest degrees
Many of the hardest degrees in the world challenge students in various ways. Scientific and patient care are assessed equally in Medicine and Dentistry, while advanced problem-solving is expected in Engineering and Physics. You'll need to fuse creativity with technical knowledge in Architecture, while studying Law will require extensive reading and critical thinking.
Ultimately, the priority should be choosing a subject you enjoy. If you are genuinely interested in a degree and it plays to your strengths, the course requirements will become more manageable. Take the time to research your options so you understand the practical and academic work required for the hardest degrees like Medicine, Maths and Physics. Doing this early will give you time to seek support to address any gaps in your knowledge.
