Is Paper 2 harder than Paper 1 in IB Computer Science?

It depends on your profile, but many students experience Paper 2 as harder because it adds time pressure to logic. In IB Computer Science, Paper 2 often exposes tiny gaps: off-by-one errors, missing edge cases, and unclear pseudocode steps. Paper 1 can feel more comfortable because you recognize the topics, but it is also where vague writing gets punished. If you want an honest answer, run a timed 25-minute set for each paper and compare your mark loss patterns. The “harder” paper is the one where your mistakes repeat.

Can I focus mostly on Paper 2 and still do well?

Only if “mostly” still leaves room for Paper 1 competence. In IB Computer Science, neglecting Paper 1 is risky because definition marks and structured explanations are predictable points. The better approach is to keep Paper 1 warm with short, high-frequency practice: a few questions, a few flashcards, one strong paragraph answer. Then you can invest extra depth into Paper 2 fluency without letting Paper 1 decay. RevisionDojo helps here because you can switch quickly between Notes, Flashcards, and Questionbank without rebuilding your plan each time.

Should I revise Paper 1 and Paper 2 on different days?

Mixing is usually better, because it mirrors how your brain actually learns: context switching forces recall. In IB Computer Science, you can do Paper 1 in the morning (explanations, case study application) and Paper 2 later (pseudocode drills, tracing). That way, your day has both “language precision” and “logic precision.” If you prefer separate days, keep a tiny daily maintenance task for the other paper (10 minutes). Consistency beats heroic weekend sessions.
