Posted: 20th December 2023
Embarking on the International Baccalaureate (IB) Diploma journey is an exhilarating step towards your academic and personal development. This unique programme, renowned worldwide, offers a rigorous yet rewarding educational experience.
As you stand at this crossroads, making informed decisions about your IB subjects is crucial. But fret not! This guide aims to shed light on how to navigate this pivotal phase, ensuring that your IB subject choices align with your aspirations and interests.
Before considering subject selection and how to choose IB subjects, it’s essential to understand the structure of the IB Diploma and how many IB subjects you can take. The programme requires students to choose six subjects – three at Higher Level (HL) and three at Standard Level (SL), offering an unmatched depth and breadth of study.
These subjects span six groups: Language and Literature, Language Acquisition, Individuals and Societies, Sciences, Mathematics, and the Arts.
Your IB journey should be tailored to your strengths and passions. Do you excel in sciences or find yourself immersed in literature? Perhaps you have an affinity for languages or a passion for the arts. Consider IB subjects where you naturally excel, as this will not only make your experience more enjoyable but also more successful.
Are you aiming for a specific university course or career path? Certain university programmes may require specific IB subjects. For instance, if you’re aiming for a career in engineering, subjects like Physics and Higher Level Maths are often prerequisites. Research what are the ib subjects required for your desired field and university options, and align your subject choices accordingly.
While it’s tempting to choose all of your favourite subjects, it’s vital to maintain a balanced curriculum. The IB Diploma’s holistic approach encourages a broad and balanced education. Choose a mix of subjects from different groups to ensure a well-rounded academic profile, as it’s this that will get you truly noticed.
Don’t hesitate to seek advice from teachers, IB coordinators, or even alumni. They can provide insights into the course content, workload, and how certain subjects complement each other. Their experiences can be invaluable in helping you make an informed decision.
Each IB subject has its unique content and assessment criteria. Familiarise yourself with these to ensure they align with your learning style and academic preferences. If you enjoy coursework-based assessment, for example, look for what are the IB subjects with significant internal assessment components like Art or History.
The IB Diploma is challenging, and while it’s important to push your limits, it’s equally crucial to be realistic about your capabilities. Striking a balance between challenging and manageable subjects will help you maintain a healthy academic workload and bring you a greater sense of achievement.
There’s often a debate about what are the “hardest” IB subjects. However, as we know, difficulty is subjective and varies from student to student. A subject perceived as challenging to one student may be a strength for another. The best advice we can give is to choose your subject options based on your abilities and interests, not on what you’ve heard about difficulty levels. Everyone is different!
While, as we’ve said, the difficulty of an IB subject is largely subjective, based on a student’s strengths and interests, certain subjects are frequently cited as being among the most challenging. This perception stems from various factors such as the depth of content, the complexity of skills required, and the rigour of assessment criteria.
What are the IB subjects that are considered more challenging? Let’s take a look at these subjects in more detail.
HL Mathematics, whether it’s Mathematics: Analysis and Approaches or Mathematics: Applications and Interpretation, is often regarded as one of the toughest IB subjects. This perception is due to the advanced level of mathematical concepts covered, the abstract thinking required, and the rigorous assessment standards. It demands a strong foundation in mathematics and a high level of analytical and problem-solving skills.
The Group 4 sciences, particularly at Higher Level, are known for their comprehensive syllabi and challenging concepts.
Physics HL is often viewed as demanding due to its abstract concepts, complex problem-solving requirements, and the application of advanced mathematical skills.
Chemistry HL challenges students with its detailed understanding of chemical processes, a significant amount of content to memorise, and the application of both theoretical and practical skills.
Biology HL requires a deep understanding of complex biological processes, extensive content coverage, and the ability to apply concepts to novel situations.
These subjects are often considered challenging due to the sheer volume of content, the need for critical thinking and analysis, and the requirement to write extensively.
History involves a deep understanding of historical events, themes, and sources, and the ability to critically analyse and synthesise this information.
Economics demands an understanding of complex economic theories and models, along with their application to real-world scenarios.
Psychology requires the understanding of various psychological theories and studies, and the ability to critically evaluate and apply them.
Subjects like Visual Arts and Music at HL are demanding due to the need for both practical skills and theoretical understanding. These courses require creativity, a significant time investment in practice and concept development, and the ability to critically analyse artistic works.
This IB subjects list covers how many subjects in IB are in each group. Now it’s time to consider why specific subjects are generally considered more challenging and how to choose IB subjects based on your future goals.

There are some key common components of these “more challenging” subjects but, equally, that ensure their rigour and reward:
Depth of Content: These subjects often cover material that is both broad and deep, requiring significant time and effort to master.
Complex Skills: Many of these subjects demand advanced skills like critical analysis, abstract thinking, and complex problem-solving.
Assessment Rigour: The IB assessment criteria in these subjects are stringent, requiring thorough understanding and the ability to apply knowledge in varied contexts.
Time Management: The workload for these subjects can be intense, necessitating strong time management and organisational skills.
Despite their challenges, these subjects can be incredibly rewarding. They provide opportunities for deep intellectual engagement, foster critical thinking, and prepare students well for higher education and future careers. The key is to approach them with dedication, effective study strategies, and a willingness to seek help when needed.
Making the best subject selection in the IB Diploma for university study, especially if you are aiming for the world’s top universities, requires strategic planning and a deep understanding of your academic and career goals. Here’s how to choose IB subjects in a way that ensures your selection aligns with your aspirations to study at elite universities.
Specific Course Prerequisites: Start by researching the prerequisites for the courses you’re interested in at your target universities. For example, engineering courses might require Higher Level (HL) Mathematics and Physics, while medical studies often require Chemistry and Biology.
Preferred Subjects: Some universities have preferred subjects for certain courses. For instance, a program in Economics might favour students who have taken Mathematics at a higher level.
General Requirements: Top universities often look for a well-rounded curriculum. Ensure that your subject choices reflect a balance across different disciplines.
Choosing Higher Level Subjects: Opt for HL subjects in areas that align with your intended field of study. HL courses are more in-depth and are often favoured by top universities for their rigour.
Balancing the Workload: While it’s important to challenge yourself, be careful not to overburden yourself with too many HL courses, which could impact your overall performance.
Critical Thinking and Analysis: Subjects like Theory of Knowledge (TOK) and Extended Essay (EE) are critical components of the IB that help develop research, critical thinking, and analytical skills, which are highly valued by top universities.
Language Proficiency: Proficiency in a second language, demonstrated by taking a Language B or even Language A course, can be a significant advantage, especially for universities in non-English speaking countries.
Align with Career Goals: Choose subjects that align with your career aspirations. For instance, if you’re interested in humanities, History and Literature would be pertinent choices.
Extracurricular Activities: Engage in extracurricular activities that complement your IB subjects and demonstrate your commitment and passion for your chosen field.
Globally Recognised Subjects: Some subjects are universally recognised for their rigour, such as Mathematics, Sciences, and Economics. These are often a safe bet for students targeting international universities.
Cultural and Global Awareness: Subjects that promote an understanding of different cultures and global issues, like Geography or Global Politics, can be beneficial for applications to universities that value global perspectives.
Consult with IB Coordinators: They can provide valuable insights into how your subject choices align with university requirements and offer advice on balancing your workload.
Speak to Alumni: Engaging with alumni who have successfully gained admission to top universities can provide practical insights into the application process and how specific subject choices benefited them.
Selecting your IB subjects is more than just fulfilling diploma requirements; it’s about strategically positioning yourself for success at top universities. Remember, it’s not about choosing what are the “hardest” IB subjects, but aligning your subject choices with your future academic and career goals, showcasing your strengths, and developing key skills, you’ll be well-prepared to embark on the next exciting phase of your educational journey.
Remember, while academic performance is crucial, top universities look beyond the IB subjects list and value well-rounded individuals with diverse interests and a passion for learning. Balancing academic rigour with personal interests and extracurricular activities will make your application stand out.
The IB Diploma is more than just an academic programme; it’s a journey of self-discovery and personal growth. Embrace this opportunity with enthusiasm and an open mind, and you’ll find the experience both enriching and rewarding.
