IB Programme Complete Guide

From IBDP structure to subject selection, from scoring to university recognition — this examiner-written guide helps you fully understand the IB Diploma Programme.

What is the IB Programme?

The International Baccalaureate (IB) is a non-profit educational foundation established in 1968, headquartered in Geneva, Switzerland. The IB aims to develop internationally minded, critically thinking, lifelong learners.

The IB Diploma Programme (IBDP) is a two-year curriculum for students aged 16-19, recognized by 5,000+ universities across 140+ countries, including all Ivy League schools and Oxbridge.

💡 Key Fact: Over 170,000 students sit IBDP exams globally each year. IB students typically have higher acceptance rates at top universities compared to non-IB students.

Three Core Components

TOK (Theory of Knowledge): Develops critical thinking. 1,600-word essay + exhibition (950-word commentary).

EE (Extended Essay): 4,000-word independent research paper on a topic of your choice.

CAS (Creativity, Activity, Service): 18 months of extracurricular engagement across three strands.

IB Scoring System

Each subject: 1-7 points. Six subjects = max 42. TOK + EE matrix = up to 3 bonus points. IBDP maximum: 45 points.

Diploma requires ≥24 points plus completion of TOK/EE/CAS. Top universities typically expect 38-42 points.

🔑 Subject Selection Tip

Choose 3 HL (240 hours) and 3 SL (150 hours). HL subjects go deeper and are weighted more by universities. For STEM applicants, Math HL and at least one Science HL are strongly recommended.
