Easiest and Hardest IB Courses

The International Baccalaureate® (IB) Diploma Programme (DP) is a well-respected high school program that has been around since 1968. It's designed for students aged 16-19 and aims to prepare them for university and beyond. The program includes six different subject areas, plus some core requirements: Theory of Knowledge (TOK), Creativity, Activity, Service (CAS), and the Extended Essay.

IB students often go on to succeed in higher education at higher rates than their peers, thanks to the program's focus on developing well-rounded, capable individuals.

However, not all IB courses are created equal. Some are easier and more straightforward, while others are known for being particularly challenging. In this blog, we’ll look at recent data to help you understand which IB courses are considered the easiest and which ones are the hardest. This will help you choose the courses that best fit your strengths and interests.


When choosing IB subjects, it's important to consider your interests, strengths, and future academic goals. The IB Diploma requires students to choose six subjects, with three taken at the Higher Level (HL) and three at the Standard Level (SL). The subjects are chosen from six groups:

  1. Language and Literature: This can be your first language or literature course.
  2. Language Acquisition: A second language, which could be a new language or one you've previously studied.
  3. Individuals and Societies: Subjects like History, Geography, Economics, Psychology, etc.
  4. Sciences: Options include Biology, Chemistry, Physics, Environmental Systems and Societies, etc.
  5. Mathematics: Either Mathematics: Analysis and Approaches or Mathematics: Applications and Interpretation.
  6. The Arts: Choices like Visual Arts, Music, Theatre, or an additional subject from another group.

Balancing your subjects to align with your interests and university aspirations is key. For example, if you plan to pursue engineering, focusing on HL Mathematics and Physics would be wise. If you’re interested in humanities, History and Literature at HL might be better suited.

How IB Courses Are Graded

In the Diploma Programme (DP), students get grades from 1 to 7 for each course, with 7 being the best. To get their final diploma, students need to add up their grades from all their courses. They must earn at least 24 points overall and meet specific requirements, including completing three key components of the DP.

Students do not qualify for a diploma if they meet any of the following criteria:

  • Score a 1 in any subject
  • Score more than two 2’s in any subject
  • Score more than three 3’s or lower in any subject

Converting an IB score to a GPA is not straightforward, as different schools and countries may use different conversion scales. However, a general guideline is:

  • 7 in HL: Equivalent to an A or A+ in GPA terms, often considered a 4.0.
  • 6 in HL/SL: Roughly equivalent to an A or A-, typically a 3.7-3.9 GPA.
  • 5 in HL/SL: Similar to a B or B+, translating to a 3.0-3.6 GPA.
  • 4 in SL: Usually considered a C or C+, around a 2.0-2.9 GPA.

Keep in mind that the conversion might vary, so it’s best to check with specific universities or consult your school's guidance counselor for more precise information.

Factors Influencing Course Difficulty

Several factors can influence how difficult an IB course might feel:

  • Background Knowledge: Students with a strong background in a particular subject may find related courses easier. For example, those proficient in mathematics may handle Mathematics AA better.
  • Interest and Engagement: Courses that align with a student's interests are often perceived as less difficult. Passion for a subject can make studying and understanding the material more enjoyable.
  • Support and Resources: Access to resources such as tutoring, study groups, and teacher support can significantly affect a student's ability to succeed in challenging courses.

What Is a Good IB Score for Top Universities?

A good IB score depends on the university and the program to which you are applying. Generally:

  • **Top Universities (e.g., **Ivy League, Oxbridge): A score of 38–40 or higher out of 45 is often required. Competitive programs might even expect scores above 40, particularly in subjects related to your chosen field of study.
  • Highly Selective Universities: A score of 36–38 can be competitive, depending on the specific course and other application components like extracurriculars, personal statements, and interviews.
  • Good Universities: Scores of 32–35 are often sufficient for many reputable institutions, though this can vary by program.

Universities also consider your HL scores individually, especially in subjects relevant to your intended major.
