When choosing IB subjects, students often divide options into two categories: popular and unpopular. Popular subjects feel safe and familiar, while less popular ones are often seen as risky or difficult.
But this way of thinking is misleading.
In reality, the difference between popular and unpopular IB subjects has far less to do with difficulty than students assume. What really matters is how expectations, competition, and preparation change depending on cohort size. This article breaks down the real differences and explains how students can succeed in either situation.

What Makes an IB Subject “Popular”?
IB subjects tend to be popular for practical reasons rather than academic ones.
Common reasons include:
- The subject is compulsory or widely required
- Schools offer it consistently
- Students studied it before the IB
- It feels accessible or familiar
- It aligns with common university pathways
Subjects like English A, History, Business Management, Psychology, and Biology fit these criteria, which explains their large global enrolment.
Popularity reflects comfort and availability — not ease.
Why Some IB Subjects Are Less Popular
Less popular IB subjects usually have lower enrolment due to:
- Limited school availability
- Strong prerequisite knowledge
- Higher perceived difficulty
- Niche academic interest
Subjects involving advanced mathematics, abstract reasoning, or specialised skills often attract fewer students. This does not mean they are poorly designed or unfairly assessed.
Low enrolment simply reflects who feels confident choosing them.
How Popularity Changes the Classroom Experience
The classroom experience can feel very different depending on subject popularity.
In popular subjects:
- Class sizes are larger
- Teacher attention is more divided
- Feedback may be less individualised
- Competition is more noticeable
In less popular subjects:
- Classes are often smaller
- Students receive more targeted feedback
- Teachers can adapt lessons more easily
- Strong students stand out quickly
Neither environment is better — they simply suit different learners.
Does Popularity Affect IB Grading?
This is one of the biggest myths in the IB.
IB grading is:
- Criterion-based
- Standardised across subjects
- Moderated internationally
You are not graded relative to how many students take your subject. A well-structured, well-argued response earns marks regardless of cohort size.
What does change is how easy it is to stand out. In popular subjects, differentiation is tougher. In smaller cohorts, strong work is more visible.
The Real Trade-Off Students Face
The real difference between popular and unpopular subjects comes down to trade-offs.
Popular subjects offer:
- More peer discussion
- Familiar content
- Abundant teaching experience
But they also involve:
- Strong competition
- High examiner expectations
- Less tolerance for vague answers
Less popular subjects offer:
- More individual attention
- Clearer differentiation
- Strong alignment with specific strengths
But they may require:
- Greater independence
- More self-directed revision
- Fewer external resources
Neither path is inherently better.
What Actually Determines IB Success
Regardless of subject popularity, the same factors determine success:
- Understanding command terms
- Knowing how marks are awarded
- Practising exam-style questions
- Learning how to structure answers
- Acting on feedback consistently
Students who master these skills outperform others in both popular and unpopular subjects.

In both cases, the goal is the same: consistent, high-quality performance.
Frequently Asked Questions
Should popularity influence my IB subject choice?
It should inform your decision, not control it. Popularity helps you understand competition and expectations, but interest and ability matter more.
Are unpopular subjects safer for scoring high grades?
Not automatically. Smaller cohorts can help strong students stand out, but success still depends on preparation and exam technique.
Is it harder to get help in less popular subjects?
It can be, but structured platforms like RevisionDojo close that gap by providing clear guidance and targeted practice.
Final Thoughts
The real difference between popular and unpopular IB subjects is not difficulty — it is environment. Success comes from choosing subjects that suit your strengths and preparing with intention.
When students focus less on trends and more on technique, subject popularity fades into the background. With the right strategy and the right support, any IB subject can become a strength — and RevisionDojo is designed to make that happen.
