Top 10 hardest science courses to study in the world in 2021

hardest science courses

Many students who join university to study any science course do not complete it. Instead, a majority of them drop the programme in their second year because science courses are complex. The difficulty in the courses arises from the abstract and dynamic nature of the concepts covered. Furthermore, the hardest science courses have a lot of content and require teacher-centred training and time dedication from the learner.

1. Physics

Physics is the hardest undergraduate degree in the world to take at any university. One reason for this is that it heavily relies on conceptual understanding of the subject matter. But another factor that makes it even more challenging is that it is the basis of many other sciences, including astronomy and chemistry.

Before a student can enrol for a degree in physics, they must have a minimum GPA of 3.0 or an average grade of B (plain) or better at high school. Also, a student must have passed with at least a B (plain) in Physics and Mathematics. After graduating, an individual can work in many fields as a physics teacher, astronomer, researcher, sound engineer, or nanotechnologist.

2. Chemistry

Chemistry is one of the most challenging science courses because it is a central science. In other words, it joins together biology and medicine, physics and mathematics, and environmental sciences. Furthermore, the abstract nature of the chemical concepts involved makes it complex. Therefore, the study requires time, dedication, understanding of the subject matter, and motivation to learn.

A requires a GPA of at least 3.1 or a mean grade of B (plain) to enrol. They must also pass in Mathematics and Chemistry plus either Physics or Biology. But once a person graduates, they can work as a chemistry teacher, chemical engineer, toxicologist, water chemist, analytical chemist, or synthetic chemist.

3. Computer Science

Computer Science is the hardest science degree to study because it requires a deep understanding of challenging topics like computer software, technology, algorithms, statistics, and learning programming languages. All these subjects need students to put in a lot of time and have enough motivation to perform well.

You can enrol to study Computer Science if you have a GPA of 3.2 or a mean grade of B+ at high school. Some institutions also require students to have passed at 70% in four subjects, including Maths and Physics. A student can work as a software engineer, data and application analyst, cyber security specialist, or game developer upon graduation.

4. Biology

Biology is a tricky science course to study because it is broad and focuses on studying life from different perspectives. It has many branches and sub-disciplines that a student must learn and understand. Moreover, the programme has some highly-focused areas that require lots of time to study, research, and prepare for exams.

To study a degree in biology, a student requires a minimum GPA of 3.0 or a mean grade of B (plain). It is also necessary to have passed in Biology, English, and Mathematics or Physics and Chemistry. After graduating, the degree can help a person become a biology teacher, pharmacologist, research scientist, health educator, or genetic counsellor.

5. Nursing

Nursing is the hardest science major because students study science topics, including chemistry, psychology, anatomy, and physiology. Furthermore, the coursework is long and complex because it involves a lot of lab work, visiting hospitals, and working with patients.

A student can study a degree in nursing if they have a GPA of at least 3.0 or a mean grade of B (plain). Furthermore, they must have passed in Biology, Chemistry, English, and Mathematics. After graduating with a nursing degree, one can work as a nurse, paramedic, midwife, or physician associate.

6. Neuroscience

Neuroscience is the most difficult course in the world because it requires a lot of memorisation and terminology. Furthermore, its core classes consist of advanced subjects like mathematics, chemistry, and biology.

Before enrolling for a neuroscience degree at the college level, a student must have a strong background in Chemistry, Biology, Mathematics, and English Language. The advantage of a neuroscience degree is that it offers an excellent starting point to a career in research science, psychology, and medicine. For example, one can become a dentist, chiropractor, neuropsychologist, or food scientist.

7. Astrophysics

Astrophysics is a branch of physics. But what makes the course more challenging is that it involves a lot of mathematics and physics at an advanced level. Also, the subject requires a lot of memorisation, calculations, and late-night studies.

A student who wants to do Astrophysics at the university must have a solid mathematics and physics background. In other words, they need to have passed the two subjects with at least 80%. But once they graduate, they can work as an astrophysicist, physics teacher, astronomer, astronaut, or an aerospace research specialist.

8. Biomedical Engineering

Biomedical Engineering presents itself as the most difficult science because it pairs biology with engineering. It teaches students to design medical devices and therapies, plan experiments, analyse and interpret data, and use engineering principles to develop solutions. Thus, a student needs a lot of motivation, concentration, and time dedication to succeed.

As a student, you must have a GPA of at least 3.2 to study Biomedical Engineering or a mean grade of B+, with a higher score in Mathematics, Biology, English, or Physics and Chemistry. After graduating, the degree can help you become a biomaterials engineer, biomedical researcher, or medical imaging consultant.

9. Molecular Engineering

Molecular Engineering is a challenging course to study because it is an emerging field of study. Furthermore, the degree is highly interdisciplinary because it combines many aspects of chemical, electrical, and mechanical engineering and physics, chemistry, mathematics, materials science, and bioengineering. Thus, a student must study all these subjects, which can be challenging.

Since it is an engineering course, a student requires a GPA of at least 3.0 to study Molecular Engineering. They must also have higher grades in all the required subjects of Mathematics, Chemistry, Biology, and Physics. Upon graduation, an individual can work as a mechanical engineer, nanotechnologist, researcher, or robotics expert.

10. Mathematics

Mathematics is the hardest science in the world and is probably the science with the most applications in other fields. The course is more challenging because it requires logical reasoning and constant training, which many people do not have the time to do it.

You can pursue a major in Mathematics if you have a GPA of at least 3.0. Also, you must have passed in Mathematics with at least 75% to enrol for the programme. After you graduate, the degree will help you become a mathematics teacher, accountant, statistician, economist, or market researcher.

The hardest science courses are also the most rewarding. When you complete a science major, it opens up opportunities for well-paying jobs in different fields. But degree programmes like computer science, physics, chemistry, biology, mathematics, molecular engineering, biomedical engineering, and nursing require a lot of time commitment and motivation to complete at the university level.

Tuko.co.ke shared an article about the 15 most marketable courses in Kenya in 2021. Many people who join institutions of higher learning often think that all courses are equal. That is not the case. Some fields that were once popular aren’t in demand in the job market nowadays due to technological advancements or the number of graduates being higher than the available positions.

The most marketable courses in Kenya are based on the growing economies and the availability of professionals. This is not to suggest that these are the only courses you can undertake. In addition, the choice of an institution may vary from one person to another, but doing a background check is vital.
