A full abstract reasoning test: twenty figure questions in 15 minutes, 45 seconds each. The question types are mixed, as in most real tests, so the first job each time is to recognize the type.
Work through the same checklist every time: count the shapes, then check position and rotation, then shading, then size. Most rules use one or two of these. If nothing appears within 30 seconds, eliminate the options that break the one rule you're sure of, pick, and move on.
