Introduction
The IB Computer Science syllabus for 2025 onward introduces updated assessment formats and a sharper focus on coding, applied technology, and databases. With these changes, students often ask: “Which textbooks should I use to prepare?”
While no textbook alone guarantees success, the right resources can provide structured explanations, worked examples, and exam-style practice. This guide highlights the best textbooks for the 2025 IB Computer Science syllabus, along with how to use them effectively.
What Makes a Good IB Computer Science Textbook?
When choosing a textbook, look for:
- Alignment with the 2025 IB syllabus.
- Clear explanations of Java/Python code and pseudocode.
- Coverage of databases, networks, and SDLC.
- Practice questions with IB-style command terms.
- IA support with step-by-step project guidance.

- Summarize key definitions on flashcards.
- Pair one comprehensive textbook with concise resources like RevisionDojo notes.
Frequently Asked Questions
1. Do I need more than one textbook?
Not necessarily. One solid textbook plus concise notes (like RevisionDojo) is enough. Some students prefer a second resource for alternate explanations.
2. Which is better for coding — Oxford or Cambridge?
Both are strong, but Cambridge provides more step-by-step pseudocode examples, while Oxford has better theory explanations.
3. Do I need to buy HL-specific resources?
Yes, if you’re in HL. HL content goes deeper into algorithms, OOP, and data structures. Ensure your textbook covers HL extensions.
4. Are RevisionDojo notes a replacement for textbooks?
No — they’re designed as revision boosters, not a complete syllabus replacement. They’re best used alongside a core textbook.
Conclusion
The best IB Computer Science textbooks for the 2025 syllabus are the new Oxford Course Companion. Pair them with RevisionDojo IB Computer Science Notes and our full Textbook Guide for 2025 for complete coverage.
With the right balance of textbooks, notes, and past paper practice, you’ll be ready to tackle both Paper 1 and Paper 2 confidently.
