Introduction
With the removal of Paper 3 from the new IB Computer Science syllabus, HL students now focus entirely on Paper 1 (Concepts & Case Study) and Paper 2 (Computational Thinking & Problem Solving). Together, they account for 80% of your final grade Preparing effectively for both papers is essential if you want to score a 7.
In this guide, we’ll walk through each paper’s structure, share proven strategies for preparation, and explain how RevisionDojo resources can help you master content, timing, and exam techniques.
Overview of HL Paper 1 & Paper 2
According to the IB's latest assessment model:
Paper 1 (HL)
- Lasts 2 hours and contributes 40% of your final grade
- Divided into:
- Section A: Core concepts (systems, networks, databases, machine learning) — short and extended responses.
- Section B: Case-study-based questions, requiring analysis, ethical evaluation, and application.
Paper 2 (HL)
- Lasts 2 hours, worth 40% of your grade
- Focuses on problem-solving, algorithmic thinking, and programming. There are different versions for Java and Python students
Quick Start Checklist
To prepare effectively:
- Know the structure and weightings of each paper.
- Practice both short-answer theory and extended-case study responses.
- Master pseudocode and algorithm-writing, tailored to your language (Java or Python).
- ⏱ Time yourself under exam conditions.
- Dive deep into both the core concepts and exam-style applications.
Strategic Preparation for Paper 1
- Actively study concept theory including system fundamentals, networks, databases, and machine learning.
- Practice command terms — differentiate between "describe", "explain", and "evaluate"
- Routine case study practice:
- Annotate and dissect case studies.
- Practice questions that require ethics or impact evaluation tied directly to the study.
- Use timed mocks to build speed and analysis skills
Strategic Preparation for Paper 2
- Handwrite pseudocode daily, using IB conventions.
- Focus on algorithmic thinking, searching, sorting, recursion, and data structures.
- Practise using language-specific versions (Java or Python) as allowed in exams
- Complete mixed past-paper questions under time constraints and review against mark schemes
Common Exam Mistakes to Avoid
- Static memorization — lack of application.
- Spending too much time on one section, risking incomplete answers.
- Misreading command terms or question requirements.
- Weak pseudocode formatting or logic inconsistencies.
How RevisionDojo Helps You Excel
RevisionDojo aligns perfectly with HL exam needs:
- Topic-aligned revision notes for HL content and case studies.
- Exam-style practice for command terms, structured theory, and case analysis.

- Timed mock exams to simulate real exam conditions.
FAQs
Q: How much should I rely on past papers?
Practice extensively — they are invaluable for getting used to question wording, structure, and timing. Use them actively, not passively
Q: Should I prioritize Paper 1 or Paper 2?
Balance your prep. Paper 1 covers core concepts and case study evaluation; Paper 2 is more coding-logic focused — both are equally weighted.
Q: Are paper structures same each exam?
Yes, the structure is consistent per syllabus, though exact questions and case studies change. Understanding format is key.
Conclusion
HL Paper 1 and Paper 2 together form the backbone of your IB Computer Science grade. Focus on mastering core content, honing pseudocode skills, and reflecting through case studies — all with time-managed practice. With RevisionDojo’s structured resources, you’ll feel prepared and confident walking into the exam.
