General Strategies for the Reading Test
- Read the passage first. Skim the introductory and concluding paragraphs to grasp the main idea before tackling individual questions.
- Underline keywords. When a question asks about tone, purpose, or inference, locate the exact phrase in the text that supports your choice.
- Eliminate clearly wrong answers. Even if youre unsure, crossing out choices that contradict the passage often leaves a single option.
- Watch for but and however. These signal contrast and often point to the authors nuanced stance.
- Time management. Allocate roughly one minute per question; if a question stalls you, move on and return if time permits.
