6 min read

Introduction

If you’re preparing for the International Baccalaureate syllabus, you’re entering one of the most rigorous and rewarding academic programs in the world. The IB isn’t just about memorizing facts—it’s about critical thinking, global awareness, and developing skills that extend far beyond the classroom. Still, understanding the IB syllabus can feel overwhelming, especially with so many core requirements and subject choices.

This guide breaks down everything you need to know about the International Baccalaureate syllabus in 2025: the core elements, subject groups, assessment strategies, and practical tips to stay on top of your workload.

Quick Start Checklist for the IB Syllabus

Here’s a fast reference for navigating the IB syllabus successfully:

  • Familiarize yourself with the six subject groups and how they fit into your schedule.
  • Understand the three core components: Theory of Knowledge (TOK), the Extended Essay (EE), and CAS (Creativity, Activity, Service).
  • Choose Higher Level (HL) and Standard Level (SL) subjects wisely—balance your strengths with challenges.
  • Review past papers and marking schemes regularly to align with IB expectations.
  • Use structured revision tools like RevisionDojo resources to simplify complex topics.
  • Stay consistent with CAS reflections and EE milestones to avoid last-minute stress.

The Structure of the International Baccalaureate Syllabus

The International Baccalaureate syllabus is designed around two major parts:

1. The Six Subject Groups

Every IB Diploma student studies subjects across these groups:

  • Studies in Language and Literature – usually your best language.
  • Language Acquisition – second or third languages.
  • Individuals and Societies – history, economics, psychology, etc.
  • Sciences – biology, chemistry, physics, ESS.
  • Mathematics – AA or AI, at HL or SL.
  • The Arts – visual arts, theatre, music (or an additional subject from another group).

2. The Core Requirements

The IB core is what sets the program apart:

  • Theory of Knowledge (TOK): Explores how we know what we know, connecting disciplines.
  • Extended Essay (EE): A 4,000-word independent research paper.
  • CAS (Creativity, Activity, Service): Engagement outside academics to build balance and responsibility.

Together, these elements create a holistic learning experience, preparing students not just for exams but for life.

How Assessments Fit Into the IB Syllabus

Assessments are a mix of internal assessments (IA) and external examinations.

  • External exams at the end of your two years test your mastery of the syllabus.
  • Internal assessments (like lab reports, investigations, or oral work) are moderated by the IB.
  • The core contributes additional points—TOK and EE together can add up to 3 bonus marks.

Many students find success by practicing with structured materials. For instance, our RevisionDojo IB prep guides give clear examples of what examiners look for.

Tips for Mastering the IB Syllabus

  • Plan early: Map out your syllabus deadlines alongside CAS and EE checkpoints.
  • Revise smartly: Don’t just reread notes—test yourself, summarize topics, and use active recall.
  • Balance workload: Too many Higher Levels can overwhelm—aim for a mix that stretches but doesn’t break you.
  • Use examiner reports: They reveal common mistakes and high-scoring strategies.
  • Stay consistent with CAS: Logging hours throughout the program prevents panic at the end.
  • Leverage study strategies: Structured revision with proven IB study methods will give you an edge.
