Its coverage depends on the selected scope and available question set. A short result cannot establish complete mastery of the SL or HL syllabus. Use the syllabus checklist to track areas that have not been tested.
Build your diagnostic
IB Physics Diagnostic
Turn uncertainty into a specific revision task
Open Diagnostic when you are unsure which part of a topic is causing difficulty. Choose your Physics level and an available scope. Treat the result as evidence from that set of questions, rather than a complete assessment of everything you know.
Look beyond whether an answer is correct. If a force diagram omits a force, return to the physical model; if the diagram is sound but the calculation fails, check signs, rearrangement and units. For an explanation question, identify the missing causal link rather than memorising a longer answer.
Use a diagnostic result constructively
Choose a meaningful scope
Select SL or HL and a topic you have encountered. A diagnostic in unfamiliar material may show what you have not yet studied rather than a persistent misunderstanding.
Attempt without copying the solution
Show enough working to expose the decision you made. Note where you guessed or could not choose a relationship.
Choose one repair
Use the available feedback to identify a specific next action. Revisit that objective, then try a fresh relevant question to check the repair.

Physics diagnostic FAQs
No. A diagnostic helps you choose what to study next. It does not reproduce the full assessment and cannot predict your final IB grade.
Use Practice when you already know the objective or skill you want to rehearse. Use Diagnostic to gather initial evidence when the weakness is less clear, then narrow your next practice session.
