When people say the IB is “a lot,” they usually mean the moment the syllabus stops being a document and starts being your life. One day you’re choosing subjects; the next you’re staring at deadlines, criteria, and unfamiliar command terms, wondering how anyone keeps it all straight.
This IB syllabus guide is designed to do something calmer: turn the 2025 IB syllabus into a map you can actually use. We’ll cover the structure, what really gets assessed, and a practical way to study so your revision feels like progress, not noise.

IB syllabus 2025 quick checklist
Use this as your reset button whenever your workload starts to blur:
-
Confirm your six IB subjects across the subject groups (and your HL/SL split).
-
Track the IB core: TOK, EE, and CAS (they do not “sort themselves out”).
-
List your internal assessments (IAs) and their rough deadlines for each subject.
-
Build a weekly routine that includes practice questions, not just reading.
-
Use one trusted platform for resources so you stop losing hours to resource hunting.
A good starting hub is the International Baccalaureate (IB) overview page, which links out to subjects and helps you stay oriented.
How the IB syllabus is structured
The IB Diploma Programme syllabus has two pillars: six subject groups and the core. Most stress comes from forgetting that both run at the same time.
The six IB subject groups (what you study)
Every IB Diploma student takes six subjects drawn from these groups:
-
Studies in Language and Literature
-
Language Acquisition
-
Individuals and Societies
-
Sciences
-
Mathematics
-
The Arts (or a second subject from another group)
Your exact mix depends on your school, but the logic stays consistent: breadth first, specialization through HL second.
If you want one place that connects subjects to exam-focused resources, start at RevisionDojo for IB and then jump into your subject hub when you’re ready.
The IB core (what makes the programme “IB”)
The IB core is three parts:
-
TOK (Theory of Knowledge): how knowledge is built, challenged, and justified.
-
EE (Extended Essay): a 4,000-word independent research project.
-
CAS (Creativity, Activity, Service): experiences and reflections that prove you can build a balanced life while studying.
Here’s the truth most students learn late: the core doesn’t just add tasks. It changes your calendar. Treat TOK, EE, and CAS like subjects with weekly time blocks, and the IB becomes manageable.

How assessment works in the IB (and why it changes how you revise)
The IB assesses you through a mix of internal and external components:
-
Internal assessments (IAs): coursework tasks marked by teachers and moderated by the IB.
-
External examinations: written papers at the end of the course.
-
Core points: TOK and EE combine for up to 3 additional points.
This matters because “knowing content” is not the same as “earning marks.” The IB rewards specific skills: applying concepts, using command terms correctly, and writing in a way that matches the markscheme.
If you want to build those skills deliberately, RevisionDojo’s Questionbank is designed for targeted practice with feedback loops. For a strategy guide, see IB Question Bank | How to Use It Effectively.
A simple IB syllabus study system (that doesn’t collapse in week 3)
The best IB students don’t have superhuman discipline. They have fewer decisions. They follow a loop.
Use the “clarity to performance” loop
-
Clarify the topic with short, syllabus-aligned explanations.
-
Lock recall with spaced repetition.
-
Apply under pressure with exam-style questions.
-
Get feedback and fix patterns.
On RevisionDojo, that maps cleanly to:
-
Study Notes for clarity
-
IB Flashcards with Spaced Repetition (SRS) for retention
-
Questionbank for application
-
Predicted Papers for exam rehearsal: IB Predicted Papers by IB Examiners (Free)
If you’re the kind of student who needs proof that notes can be exam-useful, read IB Subject Note Collections: Comprehensive Study Materials.
Practice the syllabus like it’s a set of decisions
In the IB, revision is less about “covering everything” and more about making fewer unforced errors:
-
Choose the right method for the question (explain vs evaluate vs calculate).
-
Use the correct structure (especially for extended responses).
-
Show working clearly in quantitative subjects.
-
Learn common traps and fix them early.
A practical way to do that is: one topic, then one timed set, then one review. Repeat. RevisionDojo’s Grading tools and AI Chat can support this feedback cycle, and when you need human diagnosis, Tutors can help you pinpoint what’s actually holding back marks.

Closing: make the IB syllabus your map, not your mood
The IB syllabus is not meant to intimidate you; it’s meant to define the game so you can play it well. Once you treat it like a map of skills, deadlines, and mark-awarding habits, your prep gets calmer. You stop revising randomly and start training deliberately.
If you want the most direct path from syllabus to exam confidence, build your routine around RevisionDojo: start at the IB hub, use Study Notes to stay aligned, drill with the Questionbank, reinforce with Flashcards, and rehearse with IB Predicted Papers. The IB rewards consistency, and RevisionDojo is built to make consistency easier.
