IB Physics revision guide 2026: The complete resource for every student
IB Physics revision is most effective when students follow a structured system that combines topic prioritisation, active recall, spaced repetition, and regular past-paper practice. Revision should focus not only on learning equations and concepts, but also on applying them under timed exam conditions and identifying recurring weaknesses through an error log. High-priority areas include Themes A and D together with Scientific Tools such as uncertainties, graphical analysis, and data interpretation.
This IB Physics revision guide explains how to organise topic review, use past papers effectively, choose suitable resources, and build a focused six-week plan for both SL and HL preparation.

How to structure your IB Physics revision from the start of the course
One of the most common mistakes we see is students treating IB Physics [1] revision as something that begins three weeks before the exam. In reality, effective revision is a process that should begin from the first week of the course and run in parallel with new learning.
The current IB Physics syllabus is organized around five Compulsory Themes and a set of Scientific Tools that underpin every paper. Understanding this structure early allows you to build your revision around conceptual anchors rather than isolated facts.
Your first structural priority is to map out the five themes against your school’s teaching schedule and identify which topics carry the heaviest exam weighting. Theme A (Space, Time, and Motion) and Theme D (Fields) are consistently the most mathematically demanding and appear across multiple question types on all three papers.
A practical starting point is to create a master revision document at the beginning of each new theme. Record the key equations from the Physics Data Booklet, the core physical laws, and the common question types you encounter in class. This living document becomes your personal IB Physics revision plan that you refine throughout the course.

Topic-by-topic revision checklist for IB Physics SL and HL
A reliable IB Physics topic checklist helps you track mastery rather than simply tracking time spent studying. The goal is to be honest about the difference between topics you recognize and topics you can actually solve under exam conditions.
The table below outlines the five Compulsory Themes, the key subtopics within each, and the relative priority level for revision time allocation.
| Theme | Key Subtopics | Priority Level |
|---|---|---|
| A: Space, Time, and Motion | Kinematics, Newton’s Laws, Momentum, Work-Energy, Rotational Dynamics (HL) | Very High |
| B: The Particulate Nature of Matter | Thermal Physics, Ideal Gases, Phase Transitions, Quantum (HL) | High |
| C: Wave Behaviour | Wave Properties, Optics, Doppler Effect, Standing Waves, Resolution | High |
| D: Fields | Gravitational, Electric, Magnetic Fields, Electromagnetic Induction (HL) | Very High |
| E: Nuclear and Quantum Physics | Radioactive Decay, Nuclear Reactions, Particle Physics, Quantum Phenomena | Medium-High |
| Scientific Tools | Measurements, Uncertainties, Graphical Analysis, Data-Based Questions | Critical |
For IB Physics SL HL revision, HL students carry an additional burden with deeper mathematical extensions in Themes A, B, C, and D. Topics such as rotational dynamics, electromagnetic induction, and quantum mechanics require a separate revision block and cannot be lumped together with SL content.
One critical detail often overlooked is the Scientific Tools strand. Many students treat uncertainties and graphical analysis as background knowledge, but this material is directly assessed in Paper 1B and forms a significant component of the Internal Assessment. Build it into your checklist as a standalone, high-priority revision block.

How to use past papers effectively in your IB Physics revision
Past papers IB Physics revision is the single most high-yield activity you can do in the final third of the course. However, the way most students use past papers is deeply inefficient.
The most common approach is to sit a paper, mark it quickly, circle the wrong answers, and move on. This approach produces very little learning because it skips the diagnostic stage entirely.
A more effective method has three distinct stages. First, complete a full timed paper under genuine exam conditions, with your data booklet but without additional notes. Second, mark your paper rigorously using the official markscheme and record every question you lost marks on in a dedicated error log. Third, trace each error back to its root cause: Was it a conceptual gap, a calculation mistake, a misread question, or a time management issue? Each root cause requires a different corrective action.
When to use past papers also matters. Drawing on years of experience at Times Edu, we recommend that students begin targeted topic-based past paper drilling from around the midpoint of the course, and transition to full timed papers in the final six to eight weeks before the exam.
The IBO publishes past papers from previous examination sessions, and these remain the most accurate representation of question style, language, and difficulty. Use the most recent papers closest to your exam date as mock exams, and use older papers for topic-specific drilling.

Active recall and spaced repetition strategies for IB Physics revision
Passive revision methods, such as re-reading notes, highlighting textbook pages, and watching video explanations without pausing to practice, are the most common cause of students feeling prepared but performing poorly on exam day.
Active recall IB Physics revision means forcing your brain to retrieve information from memory, rather than simply recognizing it when it appears on a page. This distinction is critical in a subject where exam questions rarely look exactly like anything you have studied before.
A structured three-step active recall method works particularly well for IB Physics.
Step 1: Equation unpacking. Open a blank page and pick one section of your Physics Data Booklet. Without looking at your notes, write out what every variable in every equation represents, its SI unit, and the physical situation in which the equation applies. This exercise reveals gaps you did not know existed.
Step 2: Causal chain mapping. Select a core concept and write a step-by-step causal explanation using arrow logic. For example, explaining why pressure increases with temperature at the microscopic level: Temperature increases, average kinetic energy of particles increases, frequency and force of collisions with container walls increase, macroscopic pressure increases. This method trains you for the “explain” and “outline” command terms that appear on Paper 2.
Step 3: Immediate past paper application. Within the same study session, complete five to eight targeted past paper questions on the exact concept you have just mapped. Commit to a written answer before checking the markscheme.
Spaced repetition IB Physics revision adds a scheduling layer on top of active recall. Instead of reviewing all topics in a linear sequence, spaced repetition schedules each topic for review at increasing intervals based on how well you know it. Topics you find difficult are reviewed more frequently; topics you have mastered are revisited at longer intervals.
Tools such as Anki can be used to create digital flashcard decks for Physics definitions, unit conversions, and conceptual explanations. However, for calculation-heavy topics, physical worked examples reviewed on paper are more effective than digital flashcards alone.

The best textbooks and online resources for IB Physics revision
Selecting the right IB Physics textbook resources is a decision that affects the quality of your entire revision period. Not all textbooks are equally well-aligned to the current IB Physics syllabus, and some popular resources are better suited to conceptual understanding while others excel at problem-solving practice.
The table below summarizes the most effective resources by purpose.
| Resource | Best Used For | Format |
|---|---|---|
| Tsokos IB Physics Textbook | Deep problem sets, rigorous practice questions, markscheme-style solutions | Physical / Digital Textbook |
| Revision Village | Syllabus-specific mock exams, topic-organized video solutions, predicted papers | Online Platform |
| GradeGorilla | Rapid micro-quizzes for Paper 1A multiple-choice consolidation | Online Platform (Free) |
| Chris Doner (YouTube) | Conceptual explanations and complex derivations for HL topics | Video |
| IBO Question Bank | Official past paper questions organized by topic and difficulty | Online (Subscription via school) |
In our experience working with international students, the Tsokos textbook is the strongest single resource for students aiming at a 6 or 7. Its questions are genuinely IB-style in their complexity and multi-step structure, unlike many revision guides that simplify problems to the point where they no longer reflect real exam demands.
A common mistake we see is students relying too heavily on a single resource. Use the Tsokos textbook for problem depth, Revision Village for mock exam practice, and GradeGorilla for rapid-fire Paper 1A concept checks. These three resources complement each other without overlap.

A six-week IB Physics revision plan for exam season
A six-week IB Physics revision plan needs to balance topic coverage, past paper practice, and exam technique work without burning out in the final week. The structure below assumes approximately two to three hours of Physics revision per day alongside other subjects.
Weeks 1 and 2: Foundation consolidation.
Revisit your master revision document for Themes A and D, the two highest-priority areas. Complete the Equation Unpacking and Causal Chain Mapping exercises for every subtopic. Do targeted past paper questions at the end of each session.
Week 3: Waves, Matter, and Scientific Tools.
Work through Themes B and C using the same active recall method. Dedicate at least four sessions specifically to uncertainties, graphical analysis, and linearizing graphs. Practice plotting T squared against l for a pendulum, and use logarithmic linearization for exponential decay problems.
Week 4: HL Extensions and Nuclear Physics (if applicable).
For HL students, this week addresses rotational dynamics, electromagnetic induction, and quantum and nuclear extensions. SL students can use this week to consolidate Theme E and review any weak areas identified from the first three weeks.
Week 5: Full timed mock papers.
Complete at least three full timed mock exams using the most recent past papers available. Mark them rigorously using the official markscheme and update your error log after each paper. Identify the top three recurring error types and dedicate targeted sessions to correcting them.
Week 6: Exam technique and selective review.
Stop introducing new content. Focus entirely on significant figures, SI unit checks, command term recognition, and graphical analysis technique. Re-read your error log from Week 5 and do one final active recall session per theme.
This six-week IB Physics revision structure is not rigid. Adjust the weekly focus based on your individual topic checklist and your mock paper error log. The purpose of the plan is to give your revision a sequence and a logic, not to prescribe exactly what every session looks like.

Frequently asked questions
What is the most effective way to revise for IB Physics?
The most effective approach combines active recall, spaced repetition, and past paper drilling within a structured revision plan. Passive revision methods such as re-reading notes produce very limited results in a subject that requires you to apply knowledge under timed conditions. Build your revision around the three-step active recall method described in this guide and supplement it with regular past paper practice using official IBO materials.
Which IB Physics topics should you prioritise in your revision?
Theme A (Space, Time, and Motion) and Theme D (Fields) should receive the most revision time because they carry heavy mathematical weighting and their concepts reappear across multiple exam questions. The Scientific Tools strand is equally critical and is directly tested on Paper 1B. Use the topic checklist in this guide to assign a priority level to each area based on your current level of mastery.
How many past papers should you complete as part of your IB Physics revision?
A realistic target is eight to twelve full timed papers in the final six to eight weeks before the exam, alongside ongoing topic-based past paper drilling throughout the course. Quality of analysis matters more than raw quantity. A single past paper reviewed thoroughly with a detailed error log produces more learning than three papers marked quickly and set aside.
What are the best free online resources for IB Physics revision?
GradeGorilla offers free micro-quizzes organized by topic and is particularly useful for Paper 1A multiple-choice practice. Chris Doner’s YouTube channel provides free conceptual explanations for both SL and HL topics. The IBO also publishes some specimen papers and subject guides on its public website, which are worth downloading and studying carefully.
How do you revise calculation skills as part of your IB Physics preparation?
Calculation revision IB Physics requires deliberate practice with worked examples rather than simply re-reading method steps. For each calculation type, practice the full process from identifying the correct equation in the data booklet, substituting values with correct units, tracking significant figures, and propagating uncertainties where required. Train yourself to check whether your final numerical answer is physically reasonable before writing it down.
Should you revise IB Physics SL and HL topics differently?
Yes. IB Physics SL HL revision requires HL students to allocate separate revision blocks for the mathematical extensions that do not appear at SL level. These include rotational dynamics and angular momentum, electromagnetic induction, quantum physics extensions, and deeper treatment of fields. HL students should use the Tsokos textbook HL problem sets specifically, as SL practice questions do not build the problem-solving depth required for HL Papers 2 and 3.
How do you create an effective six-week revision plan for IB Physics?
Start by completing your topic checklist to identify your strongest and weakest areas. Allocate the first two weeks to the highest-priority themes, the middle two weeks to remaining content and HL extensions, the fifth week to full timed mock papers, and the final week to exam technique and targeted weak-area review. Avoid introducing new material in the last two weeks. Focus on refining what you already know and correcting the specific errors your mock papers reveal.
