IB Physics flashcards

Both are necessary, but understanding should come first. You will be given a data booklet in the exam containing many key equations, so blind memorisation of every formula is less important than knowing when and how to use them. However, definitions, units, and the meaning of physical quantities do need to be committed to memory, and understanding the derivation or logic behind equations makes them far easier to apply correctly under pressure.

Work through as many past data-response questions as you can find, paying close attention to how uncertainties are expressed and how conclusions are justified from evidence. Practise drawing lines of best fit and worst-fit lines on graphs to estimate gradients with uncertainties. Review your own lab reports critically, since the skills examined in these questions mirror exactly what you practised during your internal assessment work throughout the course.

The most effective strategy is to write out the distinction between easily confused pairs in your own words and test yourself on them repeatedly using flashcards. Drawing diagrams that place both concepts side by side, for instance field lines alongside equipotential surfaces, helps your brain build separate, clear mental images. Worked examples that require you to choose between the two concepts also sharpen the distinction far better than simply re-reading definitions.

Starting structured revision around eight weeks before the exam gives you enough time to revisit every topic at least twice, complete a substantial bank of past questions, and address weak areas without panic. Leaving revision until the final two or three weeks is a common mistake in physics because the subject requires time to consolidate understanding, not just to refresh memory. Little and often, spread across several weeks, consistently outperforms intensive last-minute cramming.
