Find the tested idea
Write down the quantities, directions or conditions given in the stem before selecting a formula or rule.
Work from the evidence
Use one governing relationship at a time. For a visual question, trace the path; for a numerical question, keep units and signs consistent.
Verify before choosing
Use the wording, diagram and units exactly as given. Select an option only after it satisfies every stated condition.
OlympIQ exam lens
- ✓Extract the condition.

- ✓Check sign, unit or direction.
OlympIQ trap
Check the result against a simple limiting case, diagram direction or unit before choosing an option.
