Read the units in the choices. A right number with the wrong unit is a wrong answer. Science is optional and outside the Composite. Axis units on the figure are in axis labels and units.
Number, then unit
If the graph is in minutes and a choice is in hours, convert or skip that choice. Calculating items still need the figure’s unit, in calculating questions. Two figures that share a name can still disagree on units, in the same variable on two figures.
Data-representation passages are built on this, in data representation.
The bottom line
Match the unit as well as the number. The trap choice uses the other scale.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
