International Baccalaureate Syllabus: The Complete 2025 Guide for Students

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.
