Find the tested idea
Identify the material, change or observable property first; this decides the scientific rule to use.
Work from the evidence
Use the experiment or stated observation as evidence. Compare each option with the property, particle model or reaction condition in the stem.
Verify before choosing
Use the wording, diagram and units exactly as given. Select an option only after it satisfies every stated condition.
