Toughest Courses in the World by Specialisation

This section looks at advanced specialisations within some subjects. These areas usually require students to already have a strong foundation in the related subject. One needs to have some skills and knowledge to move into a specialised course. 

Most Difficult Medical Specialisations

Students wondering about the toughest graduation course in the world may take Medicine as an answer, as some advanced medical areas require detailed knowledge of the human body and specialised clinical training.

• Neurosurgery
• Cardiology
• Oncology
• Anaesthesiology

These are not usually separate first-degree courses. Students normally enter them after completing the required medical education and training.

Challenging Engineering Specialisations

Advanced engineering can involve highly technical mathematics, design, computing and scientific principles.

• Nuclear Engineering
• Aerospace Engineering
• Biomedical Engineering
• Robotics Engineering

Engineering at some universities allows students to move into areas such as Aerospace and Aerothermal Engineering, Bioengineering, Electrical and Electronic Engineering, and Mechanical Engineering. 

Hardest Science Specialisations

Some areas of science require students to understand several advanced concepts together.

• Quantum Physics
• Astrophysics
• Molecular Biology
• Biochemistry

Quantum Physics can be especially abstract because it deals with physical systems at the quantum level. Advanced science programmes can also involve research projects and laboratory work.

Toughest Technology Specialisations

Technology courses become more specialised as they move into areas that combine computer science, mathematics and advanced research.

• Artificial Intelligence
• Machine Learning
• Cybersecurity
• Quantum Computing

One such complex area of physics and engineering is Quantum Engineering. The Master's program at ETH Zurich combines Physics with the Information Technology and Electrical Engineering departments, and includes mandatory courses, a choice from a list of electives, a project, laboratory or industry work, and a master's thesis. 

Complex Finance Specialisations

Advanced finance can involve mathematics, statistics, economics and computer-based models.

• Quantitative Finance
• Financial Engineering
• Risk Analytics
• Mathematical Finance

These areas are often more mathematical than general finance programmes and may require strong skills in statistics, programming and financial theory.

Toughest Courses vs Toughest Entrance Exams

A difficult course and a challenging entrance exam are not the same thing. The difference is important in the case of the hardest courses in the world.

An entrance exam can help to judge many applicants, whereas a difficult course requires continuous learning and work over time. 

Here’s a table showing a comparison between the two in detail. 

Point	Toughest Entrance Exams	Toughest Academic / Professional Courses
Main Purpose	To select students from many applicants	To teach students difficult and specialised subjects
How Long?	Usually a few hours or days	Can take several months or years
What Makes It Hard?	Many students compete for limited seats, and there is limited time	Large syllabus, regular exams, projects, and practical training
Examples	Gaokao, IIT-JEE Advanced, UPSC CSE	Medicine, CFA, Chartered Accountancy (CA)

What Makes These Courses Tough?

The difficulty of some courses comes from one aspect, whereas for other courses it is a different aspect. So there is no single answer to what is the toughest course in the world. 

Sometimes, the difficulty can be assessed by the number of exams the course has, with a small number of students selected, which is considered to be tough. 

Here are the main things that can make a course hard. 

• Academic Complexity: Difficult maths, science and technical topics can make courses such as Physics, Engineering, Medicine and Data Science challenging.
• Course Workload: A large number of lectures, assignments, projects, readings and exams can make a course difficult to manage.
• Practical and Clinical Training: Courses such as Medicine, Dentistry, Nursing, Pharmacy, Engineering and Architecture may include laboratory, practical, studio or clinical work.
• Examination Difficulty: Regular exams and professional exams can be challenging because students need to understand and apply what they have learned.
• Course Duration and Professional Requirements: Some courses take several years to complete and may also require additional training, exams or professional licences.

Factors to Consider Before Choosing a Tough Course

Looking only at a list of the top 10 toughest courses in the world is not enough to choose a degree. A course may be difficult, but that does not automatically mean it is the right course for every student.

Let’s look at the main key factors that need to be considered when choosing a tough course.

• Course Duration: Check how many years the programme takes. Also check whether professional training, internships, or further study are required after graduation.
• Academic workload: Look at the subjects, the quantity of modules, assignments, projects, and the number of exams. A course that appears to be of interest might have a workload that doesn't fit your style of learning.
• Entrance Requirements: See the required subjects, grades, entrance tests, and language requirements before applying. Some universities may have separate tests for competitive courses. Cambridge Engineering, for example, requires applicants to take the ESAT.
• Practical Training: Find out whether the course includes laboratory work, clinical training, fieldwork, design projects or internships. These can take extra time but may also be an important part of learning.
• Licensing requirements: There are some careers which require more than the basic University degree. Depending upon the country, other occupations, such as medicine, law, accounting, and certain engineering professions, may have professional or licensing requirements.
• Career Opportunities: Think about what you want to do after graduation. Review the relationships between jobs, additional education, and work before you select your course.
