IB Computer Science Practice Exam 2025 – Complete Study Resource

The International Baccalaureate (IB) Computer Science Exam is an essential component for students pursuing the IB Diploma with a focus on computer science. Tackling this exam requires a solid understanding of computers, programming, and the critical theoretical concepts that define the computing world. Preparing with the right resources can make a significant difference, ensuring that students are well-equipped to navigate through the exam's challenges effectively.

Understanding the IB Computer Science Exam Format

The IB Computer Science Exam is structured to assess a student's knowledge across various domains of computer science. The exam typically comprises two or three papers depending on the level of the course (Standard Level or Higher Level). Here's a breakdown of what each level entails:

Standard Level (SL)

• Paper 1: Focuses on core topics like system fundamentals, networks, and computational thinking with 45% weightage.
• Paper 2: Involves optional topics chosen by the teaching institution with 25% weightage.
• Paper 3: While usually omitted for SL students, some teachers may incorporate additional projects or assignments.

Higher Level (HL)

• Paper 1: Similar to SL but with a more complex set of questions covering core topics, with a 40% weightage.
• Paper 2: Allows students to delve deeper into optional topics, such as databases, object-oriented programming, or web science, carrying 20% weightage.
• Paper 3: This is an advanced paper that assesses students' skills in developing complex algorithms or systems, with a 20% weightage. It includes case studies and additional projects.

What to Expect on the Exam

Understanding what to expect during the exam can help reduce anxiety and increase performance. Here are the main components to consider:

1. Multiple Choice and Structured Questions: Expect a blend of multiple-choice questions designed to test foundational knowledge, alongside structured questions that require more detailed, written responses.

2. Programming Tasks: Practical programming questions necessitating the ability to write and understand code, often tested through hands-on problem-solving.

3. Case Studies: Particularly prevalent in Paper 3 for HL students, these sections test applied knowledge where students review a given scenario and provide reasoned solutions.

4. Algorithm Development: An integral part of the exam is creating and analyzing algorithms, understanding data flows, and interpreting computational problems.
