I help students all around the world to get the best mark possible in the IB physics exams.

Did you know that in 2020 and in 2021 paper three was cancelled? We didn't do any exams on the IB Physics Option topic. Now as we go into 2023, Paper 3 is returning.

This means you must make sure that you have an option topic prepared to answer in Paper 3.

It also means you must be really, really good at Topic 1: Measurements and Uncertainties, as there's a huge section at the start of Paper 3 that's devoted pretty much to Topic 1 and practicals.

The required practicals you may be assessed on in Paper 3 are:

  1. Determine the acceleration for freefall
  2. Apply the calorimetric techniques of specific heat capacity or specific latent heat
  3. Investigate at least one gas law
  4. Investigate the speed of sound
  5. Investigate one or more of the factors that affect resistance
  6. Determine internal resistance
  7. Investigate half-life
  8. Investiate Young’s double slit experiment
  9. Investigate a diode bridge rectification circuit
