Revision plan
How to revise IB Physics
An eight-week plan for students aged 16 to 19 taking the International Baccalaureate Diploma, built around active recall and spaced repetition.
The approach
Revising IB Physics effectively means treating it as an active, problem-solving discipline rather than a body of facts to be read over. The most productive sessions combine short bursts of concept review with immediate practice on related questions, so that understanding is tested rather than assumed. Spreading revision across several weeks, returning to earlier material regularly, and being honest about which topics feel genuinely secure versus which ones only feel familiar after recently reading them, will make the difference between a good result and a great one.
Your eight-week plan
- 1
8 weeks out: audit your knowledge
Go through every topic systematically and rate your confidence honestly on each one. Use your class notes, flashcards and the data booklet to identify which equations and definitions you can reproduce without prompting and which ones you cannot. This audit prevents you from spending revision time on material you already know well while neglecting the areas that will cost you marks. Write a priority list of weak topics to address first in the coming weeks.

7 weeks out: rebuild weak foundations
Focus on the topics flagged as weakest in your audit, working through them from first principles rather than just re-reading notes. For each topic, write a concise summary in your own words, create flashcards for key definitions and equations, and then attempt a small set of exam-style questions to check whether your understanding is functional. Mechanics, electricity and waves are common areas where students discover their understanding is shallower than they thought.

6 weeks out: connect ideas across topics
IB Physics questions often draw on more than one topic at once, for example linking thermal physics to ideal gas behaviour, or combining circular motion with gravitational fields. Spend this week deliberately making connections, drawing concept maps that link related ideas across different areas of the course. Practise questions that are explicitly multi-topic and note where your reasoning breaks down. Understanding how topics relate to each other also deepens your grasp of each individual topic.
- 4
4 to 5 weeks out: intensive past paper practice
Begin working through full past papers under timed, exam-like conditions. Mark your answers honestly using mark schemes, but focus on understanding why an answer is correct rather than simply noting the mark. Keep an error log where you record every question you got wrong and the reason, whether it was a missing definition, a unit error, a sign mistake or a conceptual misunderstanding. Return to this log regularly to ensure the same errors do not recur.
- 5
2 to 3 weeks out: targeted consolidation
Use your error log to identify the patterns in your mistakes and dedicate focused sessions to those specific areas. Return to any topics that still feel uncertain and re-test yourself using flashcards and short question sets. At this stage you should also review your approach to uncertainty calculations and graph analysis, as these skills appear across many question types and are easy to neglect during topic-based revision. Revisit earlier flashcard sets to maintain retention of material covered weeks ago.
- 6
Final week: review and consolidate calmly
Avoid attempting entirely new material in the final week, as this tends to increase anxiety without meaningfully improving performance. Instead, review your summary notes, work through a small number of past questions each day to keep your problem-solving sharp, and re-read your error log to remind yourself of the corrections you have already made. Familiarise yourself with the layout of the data booklet so you can locate equations quickly under exam pressure. Prioritise sleep and steady routine over marathon study sessions.
IB Physics revision tips
- Always write out the full working for every calculation, including the substitution of values with units, because this habit both reduces arithmetic errors and mirrors the method expected in exam mark schemes.
- When revising definitions, test yourself by covering the definition and trying to write it from memory, then compare word by word, since physics definitions are often marked on the presence of specific key terms.
- Draw diagrams wherever possible when revising topics such as fields, waves and circuits, as a well-labelled diagram often clarifies a concept more quickly than a paragraph of text and is also a valuable exam technique.
- Use the data booklet actively during revision rather than memorising every equation independently, so that you become fluent at finding and interpreting the equations provided rather than arriving in the exam unsure of what is given.
- After completing a past paper question, spend as long reading the mark scheme as you spent answering it, paying attention to the precise language used in high-scoring answers and noting any alternative approaches you had not considered.
Mistakes to avoid
- Many students revise by re-reading their notes repeatedly, which creates a false sense of familiarity without building the ability to retrieve and apply knowledge under exam conditions.
- Skipping uncertainty and error analysis during revision is a frequent mistake, as these skills appear throughout the exam and are often underprepared because students find them less engaging than the main physics content.
- Focusing almost entirely on topics that feel interesting or comfortable, while repeatedly postponing the revision of genuinely difficult areas, means that weaknesses remain unaddressed right up to the exam.
