IB DP Syllabus 2026: Subject-Wise Curriculum Guide for Class 11 and 12
The IB DP syllabus for Classes 11 and 12 covers six subjects, divided into Higher Level and Standard Level courses. The curriculum include language, humanities, sciences, and math. In addition to regular classes, students also complete the ‘IB Core,’ which has a 4,000-word Extended Essay, a Theory of Knowledge (TOK) course, and Creativity, Activity, Service (CAS) requirements. To succeed in the IB DP, students need to handle Internal Assessments (IAs) and review past exam papers.
​
The IB DP is a two-year program that encourages students to think critically instead of just memorizing facts. If you are a student or parent looking to understand the IB DP 2026 syllabus, this guide will help you learn about the curriculum and how to succeed in it.
How the IB DP Works: HL vs SL and Subject Groups
Students choose six subjects, one from each group. If they prefer, they can replace Group 6 with another language, science, or humanities subject. These subjects are offered at two different difficulty levels.
​
- Higher Level (HL): Students take 3 or 4 subjects at this level, with about 240 teaching hours. HL courses cover more content and have extra assessments.
- Standard Level (SL): 2 or 3 subjects, approximately 150 teaching hours, core content with fewer extensions.
IB DP: Â Subject-Wise Breakdown
Group 1: Studies in Language and Literature
Usually, the student’s native or strongest academic language (e.g., English A Literature or Language & Literature).
- Students study a range of literature, from classic poetry to modern media, advertisements, and political speeches.
- Students do more than summarise plots. They are expected to examine how writers use different techniques to create meaning.
Group 2: Language Acquisition
A second language learned as a beginner (Ab Initio) or intermediate speaker (Language B).
- Students focus on communication, cultural understanding, and practising different types of writing, like letters, blogs, and essays.
- Students should pay attention to format rules. For Paper 1 (Writing), organising a blog entry with a title, an engaging tone, and a clear call to action can help improve their score.
Group 3: Individuals and Societies
Humanities like History, Economics, Psychology, and Business Management.
- Students read and write essays in these subjects. The updated IB history course will start in August 2026.
- For subjects like Economics and Business, students should learn real-world case studies early. Relying only on theory will not help them achieve the highest marks.
Group 4: Sciences
Biology, Chemistry, Physics, Sports Science, or Computer Science.
- Students need to understand complex ideas and analyse data.
- Their  Internal Assessment (IA)—an independent laboratory or data investigation—counts for 20% to 25% of your final grade. Students should ideally choose a topic they genuinely care about; their personal engagement is explicitly graded.
Group 5: Mathematics
Mathematics is divided into two paths. Analysis and Approaches (AA) is for calculus-focused, pure math topics. Applications and Interpretation (AI) is for statistics and practical data work.
- This section involves continuous problem-solving. AA is usually preferred for engineering/physics majors, while AI is fantastic for social sciences and business.
- A helpful tip is to learn how to use the Graphic Display Calculator (GDC) from the start. Knowing its shortcuts can make a big difference in IB math exams.
Group 6: The Arts
Visual Arts, Film, Music, or Theatre (Optional—can be replaced by an extra subject from Groups 2, 3, or 4).
- This group uses fewer traditional exams and focuses more on portfolios, curatorial statements, and creative work.
The IB Core
Finishing the Core is essential for earning the diploma. These three parts connect the whole program. Here is what students need to know.
- Theory of Knowledge (TOK): A class exploring how we know what we claim to know. Assessed via an exhibition and a 1,600-word essay.
- Extended Essay (EE): A fully independent, 4,000-word undergraduate-level research paper on a topic of your choice.
- Creativity, Activity, Service (CAS): This part encourages students to balance academics with creative activities, physical exercise, and community service.

How to Study for IBDP Class 11 vs. Class 12
To manage time well over these two years, students need to adjust their focus as they progress:
|
Timeline
|
Focus Area
|
Goal
|
|
Class 11 (Year 1)
|
Conceptual foundation, skill building, and testing out potential topics.
|
Nailing down your final HL/SL choices and locking in your EE research question.
|
|
Class 12 (Year 2)
|
Drafting IAs, finishing the EE, mock exams, and core compilation.
|
Transitioning from learning new content to intense past-paper practice.
