Introduction
One of the biggest questions IB Computer Science students ask is: “Should I focus more on Paper 1 or Paper 2?” Both exams test different skills — Paper 1 emphasizes theory, systems, databases, and case studies, while Paper 2 focuses on problem-solving, pseudocode, and algorithms.
Since each paper is worth 40% of your final grade (at HL), neither can be ignored. But depending on your strengths, you may need to balance your revision differently. This article breaks down both papers, their requirements, and how to study effectively for each.
Quick Start Checklist
- ✅ Paper 1 = theory, core concepts, and case studies.
- ✅ Paper 2 = pseudocode, algorithms, and coding logic.
- ✅ Both papers are equally weighted (40% each for HL).
- ✅ Revise based on your weakest area to balance your score.
- ✅ Use RevisionDojo resources to cover both efficiently.
Paper 1: What to Expect
Paper 1 tests:
- Core theory (systems, networks, databases, machine learning, ethics).
- Command terms like describe, explain, evaluate.
- Case study analysis (applies to both SL and HL from 2025).
Best revision strategies for Paper 1:
- Summarize theory with syllabus-aligned notes.
- Practice applying knowledge to real-world examples.
- Review case studies and practice essay-style answers.
Paper 2: What to Expect
Paper 2 tests:
- Pseudocode writing.
- Algorithmic thinking (sorting, searching, recursion, data structures).
- Problem-solving using Java or Python track (depending on school).
Best revision strategies for Paper 2:
- Write pseudocode by hand every day.
- Trace algorithms step-by-step with sample data.
- Practice past paper coding problems under timed conditions.
Should You Focus More on One?
- If you’re strong in coding but weak in theory → Spend more time on Paper 1.
- If you’re good at memorizing theory but struggle with logic → Spend more time on Paper 2.
- If you’re aiming for a 7, balance is key — aim for consistent performance across both.
Common Mistakes Students Make
- Ignoring Paper 1 because “theory is easy.” Many students lose marks on case study analysis.
- Only practicing algorithms for Paper 2 but forgetting to practice pseudocode format.
- Splitting time evenly without addressing personal weaknesses.
How RevisionDojo Helps
RevisionDojo gives you structured resources for both exams:
- Concise Paper 1 notes covering theory and case study preparation.
- Algorithm and pseudocode guides for Paper 2 practice.
- Exam-style practice questions with model answers for both papers.
This way, you don’t waste time guessing where to focus — Dojo ensures you’re fully prepared.
FAQs
Q: Which paper is harder?
It depends on the student. Some find Paper 1’s theory easier, others struggle with Paper 2’s pseudocode. Most students consider Paper 2 harder because it requires more problem-solving under time pressure.
Q: Can I score well if I focus mainly on Paper 2?
Not if it means neglecting Paper 1. Both count equally, so balance is essential.
Q: Should I revise Paper 1 and 2 on different days or the same day?
Mix both. For example, do theory in the morning and pseudocode practice in the afternoon.
Conclusion
You can’t prioritize one paper over the other in IB Computer Science — both Paper 1 and Paper 2 are equally weighted and test complementary skills. The smartest strategy is to identify your weaker area and dedicate extra time there while maintaining balance.
With RevisionDojo’s notes for Paper 1 and pseudocode guides for Paper 2, you’ll cover both exams efficiently and be well on your way to a 7.
