We are providing these GPAs to give you a reasonable idea as to the difficulty of the fields of study.


#1 Chemistry

Chemistry will overlap somewhat with biology, but it extends beyond living things. You will focus on the composition of matter, including all structures, properties and reactions. As a student, you will spend a good chunk of your time in the lab, testing and re-testing theories.

Students who study Chemistry can choose from a number of jobs, including education, research, medicine, pharmaceuticals, nursing and law. Some students opt to further their education in the field by pursuing a graduate degree.

Chemistry Pros:

  • You will have lots of hands-on learning in the lab!
  • Prepare to be proud when you make a big discovery or invention.

Chemistry Cons:

  • In Chemistry, there is a right and a wrong, and little area for middle ground or opinions.
  • The courses will rely heavily on testing, which may make it extra challenging for some students.
  • You may need a more advanced degree in order to find a job outside of the lab or teaching arenas.

mathematics courses

#2 Mathematics

A degree in math may seem a bit generic, but it’s actually quite flexible. Employers everywhere are seeking individuals who think independently, creatively and critically, and students who study math do exactly that. They also do well in statistics and algebra classes, of course.

With skills like these, you could go on to work in patent law, software engineering, animation, financial analysis, economics, computer security, market research, astronomy or any number of fields.

Mathematics Pros:

  • This is a pretty flexible field of study, and pairs well for a dual degree or minor.
  • With a degree in math, people will just assume you’re a genius.
  • A mathematician is ranked as the #2 Best Job, noting the “very good work environment, very low-stress level and very good projected growth.”.

Mathematics Cons:

  • Many jobs require a graduate degree, which will cost more and take longer to earn.
  • People will assume you are a human calculator.

#3 Economics

Economics involves the study of individual, household and organizational behavior as it relates to markets and finance. It’s about how people think and act, what makes them make the decisions they do, and so on. In this area of study, you will need to take a lot of math and statistics courses, and do plenty of critical thinking and synthesizing of data – so it is most definitely hard!

Economics students can go on to work in business, as well as technology, government, and finance for example.

Economics Pros:

  • You will be able to work in a number of different industries.
  • The critical thinking and problem-solving skills you will develop will be valuable in both your professional and personal life.

Economics Cons:

  • If you’re not a math guru – or at least someone who likes math – you will likely struggle in this field.
  • Studying graphs, charts and spreadsheets may be a little dry.

#4 Biology

Interested in all things alive? Go beyond basic frog dissection and learn about the evolution, growth, life cycles and other aspects of animals, plants, bacteria and fungi. You’ll do a lot of hands-on learning, in the lab, making new discoveries and advancing our understanding of everything that’s living. You will also need to understand the terms and processes, which means there will be a lot of memorization required.

Biology Pros:

  • There are so many specializations to choose from!
  • You’ll get to work with and learn about nature, and use advanced tools.
  • There are a variety of occupational paths, such as working in laboratories, conducting field research or teaching at the secondary or post-secondary level.

Biology Cons:

  • You will need to keep up on developments and findings that are happening outside the classroom every day.
  • There will be a lot to learn and memorize.
  • Since many biology students plan to go into the medical field, professors often try to prepare students for the rigors of medical school, making this a very demanding field of study.
  • There can be an element of danger to the field, particularly for those working with diseases and bacteria.

#5 Geology

Earth to students!  Geologists study the history of our planet and use that knowledge to make predictions about future earthquakes, floods and volcanic eruptions. They also use their knowledge to determine where and how to build highways or structures, or lay pipelines for natural gas or oil. Their work is calculated and complicated, but it can be very rewarding!

Geology Pros:

  • You can find employment with only a bachelor’s degree.
  • The field can be exciting, with hands-on exploration in the field.

Geology Cons:

  • You may need to travel to do fieldwork in remote areas.

#6 Philosophy

Get ready to stretch your brain around some big questions! What’s the meaning of life? How do we attain truth? What is human consciousness? You’ll study the ideas of famous philosophers and develop theories of your own.

Jobs in philosophy are hard to come by, so many students pair the degree with a more marketable area of study or a minor. Consider computer science, mathematics, ethics, linguistics, physics or life sciences.

Philosophy Pros:

  • You will develop strong analytical and writing skills, valuable in many jobs as well as in life.
  • You can enjoy the deep thinking involved in philosophy, while also learning skills in another field.

Philosophy Cons:

  • It may be harder to find employment outside of teaching without another area of expertise.
  • Society tends to look down on philosophy in favor of scientific facts.

undergraduate computer programming

#9 Computer Science

If you’re a techie who loves digging deep to solve complex problems, computer science may be a good fit for you. You’ll need patience and persistence, and the ability (and desire) to learn entirely new computer languages in order to solve problems and make processes more efficient.

Computer Science Pros:

  • You could work for a large insurance corporation, for Google, or for the CIA – your skills will be useful in a wide variety of industries!
  • Technology is always evolving, so there will always be a need for people skilled computer scientists.
  • You will never stop learning.

Computer Science Cons:

  • Because things are always changing, you may put a lot of time and effort into learning a language or skill only to find it’s obsolete and you need to educate yourself on the newer methods.

It will take a lot of hard work to excel in these fields of study, but the payoff could be huge!


How hard a subject maybe is quite subjective.

That being said, there are a few factors that may make one major seem harder than another, such as:

  • Number of hours spent in classes and labs (Insider tip: how to get credits quickly)
  • Number of hours spent studying
  • Stricter professors
  • Stricter grading policies

Because of the rigorous math and science courses, Science, Technology, Engineering and Math (STEM) majors are generally considered hard.

To compile our list of majors/degrees, we looked at the fields of study with the lowest average GPAs. In a recent whitepaper, Cornell University found that science majors tend to have lower GPAs, with Chemistry winning the prize for the lowest average GPA.

The difficulty of a degree plan will depend somewhat on the university.

How hard a major is will also vary by university. Different schools have different professors, different grading policies, different course material, and even different courses required to earn a degree.

Average GPAs differ between public and private colleges

A recent study found that where you attend university will impact your overall GPA, but not by as much as you might think. Students at public universities have an average GPA of 3.1 while those attending private universities have a 3.3 GPA.

The best university programs have different requirements

All degree plans are not created equal.

A Bachelor’s in Computer Science at Duke University will have different requirements than one earned at the University of Illinois.

One example of this is in the Calculus requirement:

  • Duke requires Calculus 1 & 2
  • The University of Illinois requires Calculus 1, 2, & 3

Depending on the school, you may even be required to complete four semesters of Calculus (which can be a tough subject!). Is the school that requires more Calculus credits harder? Maybe. Maybe not.

That being said, we’ve compiled our list based on averages. It should give you a general idea of which fields of study are likely to be the most challenging for most students.

GPAs by Field of Study

The following table shows the average GPA by field of study.

Major Average GPA
Chemistry 2.78
Mathematics 2.90
Economics 2.95
Biology 3.02
Geology 3.03
Philosophy 3.08
Finance 3.08
Physics 3.10
Computer Science 3.13
Mechanical Engineering 3.17
