How to Revise IB Physics With Past Papers
The most effective way to revise IB Physics with past papers is to use a repeated cycle: attempt, mark, diagnose, watch the method, and reattempt. Completing papers without studying your errors may improve familiarity, but it rarely fixes weak equation selection, unclear working, or poor use of the physics data booklet.
Past papers should therefore be treated as diagnostic teaching tools, not simply as tests. This guide explains how to practise Paper 1A, Paper 1B, and Paper 2 at SL or HL, identify where marks are being lost, and use worked video solutions to improve your method.
Understand the IB Physics paper structure
Under the current IB Physics course, first assessed in 2025, external assessment contributes 80% of the final grade. Paper 1 contributes 36%, while Paper 2 contributes 44%. The remaining 20% comes from the internally assessed scientific investigation.
The official IB Physics subject brief gives the following structure:
| Component | Question style | SL time | HL time | Final-grade weighting |
|---|---|---|---|---|
| Paper 1A | Multiple-choice questions | Part of the 1.5-hour Paper 1 | Part of the 2-hour Paper 1 | Combined with Paper 1B |
| Paper 1B | Data-based questions | Part of the 1.5-hour Paper 1 | Part of the 2-hour Paper 1 | 36% for Paper 1 overall |
| Paper 2 | Short-answer and extended-response questions | 1.5 hours | 2.5 hours | 44% |
SL and HL students encounter the same broad paper types, but HL assessment includes additional higher-level content and demands greater depth. When selecting practice, check that the paper or question set matches both your level and the current syllabus.
Older papers can still contain valuable physics, but their structure and syllabus coverage may differ. Use them selectively by topic rather than assuming that an old paper is an exact model of your present examination.
Use the attempt-mark-review-reattempt cycle
A productive past-paper session has four active stages.
- Attempt the question independently. Work without notes unless the session is deliberately open-book.
- Mark it precisely. Compare each line with the mark scheme or model solution rather than checking only the final answer.
- Study a worked method. Watch how the question is interpreted, how the data booklet is used, and how the working is presented.
- Reattempt it from a blank page. Do this later, without copying the demonstrated solution.
The fourth stage matters because understanding a solution while watching it is not the same as producing it independently. A successful reattempt shows that the correction has entered your usable exam technique.
RevisionDojo's IB Physics video library provides worked video solutions that can be used after an honest attempt. Pause before each step, predict what should happen next, and compare that prediction with the demonstrated method.
Practise each paper differently
Paper 1A: multiple-choice questions
Paper 1A tests more than rapid recall. Distractors are often based on predictable errors such as reversing a ratio, confusing a vector with a scalar, overlooking a squared quantity, or substituting incompatible units.
For each wrong answer, record why your chosen option appeared plausible. Then solve the question again without looking at the choices. This prevents answer elimination from hiding an incomplete understanding of the physics.
Effective Paper 1A review should include:
- estimating the expected magnitude before calculating
- checking dimensions and SI units
- drawing a quick diagram where direction matters
- identifying the relevant equation before entering calculator values
- explaining why the other options are wrong
Paper 1B: data-based questions
Paper 1B requires students to interpret unfamiliar information rather than reproduce a memorized experiment. You may need to extract values, interpret gradients or intercepts, process uncertainty, evaluate a relationship, or connect a graph to an underlying model.
Do not begin by searching randomly for an equation. Identify the independent and dependent variables, read the axis labels and scale, note the units, and decide what physical quantity a gradient or area represents. Show substitutions clearly because a correct final value cannot always recover marks lost through unsupported or incorrect reasoning.
Practise Paper 1B separately when possible. RevisionDojo's Paper 1B practice paper illustrates how focused data analysis can be trained without completing an entire mixed paper.
Paper 2: short and extended responses
Paper 2 rewards connected reasoning. A multi-part problem may begin with a familiar calculation and then require an explanation, derivation, comparison, or evaluation based on the same physical situation.
Write enough working to make your method visible:
- state the governing principle or equation
- rearrange symbolically when this improves clarity
- substitute values with units
- retain extra calculator digits during intermediate steps
- round appropriately at the end
- answer explanation questions using the specific physical context
For longer responses, use the command term to control your answer. Calculate requires working and a numerical result, while explain requires linked physical reasoning. RevisionDojo's Physics Paper 2 SL mock can support full-paper practice after you have repaired topic-level weaknesses.
Fix data booklet and working errors
Two of the most preventable sources of lost marks are weak data booklet use and incomplete working. Students sometimes know the relevant topic but select the wrong relationship, fail to interpret a symbol, or substitute before checking whether the equation's assumptions fit the situation.
Do not try to memorize the booklet page by page. Learn it through repeated retrieval:
- Name the principle involved, such as conservation of momentum.
- Predict the form of the required relationship.
- Locate it in the booklet.
- define each symbol in the context of the question.
- Check assumptions and units before substituting.
Watching a question worked through is especially useful here. A strong video solution reveals not only which equation is used, but also how the solver rejects unsuitable equations, translates the wording into a model, and lays out the calculation for credit.
Maintain an error log with categories rather than vague topic labels:
| Error category | Example | Corrective action |
|---|---|---|
| Concept | Treating acceleration as necessarily increasing speed | Review direction and sign, then answer three conceptual questions |
| Data booklet | Selecting an equation with incompatible variables | Locate and annotate the relevant relationship before reattempting |
| Working | Giving only a calculator answer | Rework with equation, substitution, units, and final value |
| Data analysis | Calculating gradient from points too close together | Use a large triangle and show coordinates |
| Reading | Missing “magnitude” or “initially at rest” | Underline constraints before solving |
| Timing | Spending too long on one part | Set a checkpoint and move on when it is reached |
Move from topic practice to timed papers
Starting immediately with full timed papers is inefficient if several topics remain weak. Use a three-phase progression.
Phase 1: topic clusters
Complete groups of questions on one syllabus area. The Space, time and motion questionbank, circular motion practice, and nuclear and quantum physics questionbank allow focused correction of specific gaps.
Phase 2: mixed untimed sets
Combine topics and paper styles, but permit enough time to develop complete methods. Use the IB Physics resource hub to move between questions, notes, and supporting explanations.
Phase 3: full timed simulation
Complete the correct SL or HL paper under uninterrupted conditions with the permitted materials. Mark it on the same day if possible, but calculate more than a total score: record performance by topic, paper type, command term, and error category.
A useful weekly pattern is two topic sessions, one Paper 1A speed session, one Paper 1B data session, and one longer Paper 2 or mixed-paper session. Adjust the balance according to evidence from your error log rather than spending equal time on every topic.
Common past-paper mistakes
Avoid these habits:
- Reading solutions before attempting questions. This creates recognition, not independent recall.
- Completing many papers without reattempting errors. Volume does not guarantee improvement.
- Recording only scores. A percentage does not explain what needs to change.
- Ignoring correct answers reached by weak reasoning. A lucky answer remains a vulnerability.
- Using old papers as exact current-format mocks. Older questions are often better used as topic practice.
- Watching videos passively. Pause, predict, take notes, and reproduce the method afterward.
Jojo AI can help explain why a method failed or generate a focused follow-up question, but compare assessment decisions with the available mark scheme and your teacher's guidance. The aim is to develop reasoning that you can reproduce under examination conditions.
Conclusion
To revise IB Physics effectively with past papers, attempt questions independently, mark the working closely, diagnose the precise error, study a demonstrated method, and reattempt from scratch. Give separate attention to Paper 1A speed and concepts, Paper 1B data analysis, and Paper 2's extended calculations and explanations.
RevisionDojo's Physics Questionbank, Jojo AI, mock papers, and per-question physics video solutions can support this feedback cycle. Start with the question type producing the most repeated errors, then move toward complete timed papers as your method becomes reliable.
