Summary Techniques
Important Facts

- Maintain the author's original meaning and tone
- Keep summaries significantly shorter than the original text
- Include only the most important supporting points
Key Definitions
Term
Summary
Example
3-paragraph article becomes 2-3 sentences capturing key points
Definition
A brief restatement of main points in your own words, shorter than the original
Term
Paraphrasing
Example

Definition
Restating information using different words while maintaining the same meaning
Diagrams To Know
- Summary pyramid showing hierarchy of information importance
Must Remember
- Every paragraph has exactly ONE main idea
- Main idea = Topic + Author's argument about the topic
- Look for contrast signal words (but, however) - they often introduce the real main idea
- First and last sentences are prime locations for directly expressed main ideas
- For implied main ideas, find repeated words/concepts and infer the common theme
- Supporting details are always more specific than the main idea
- Test your main idea by checking if all details support it
- Summaries should be in your own words and significantly shorter
- Don't confuse topic (what it's about) with main idea (what's being said about the topic)
- When in doubt, ask 'What is the author's main point about this topic?'
Last Minute Tips
- Time pressure: Read first sentence, last sentence, then middle - main idea is usually in one of these positions
- If first sentence seems too broad or introduces the topic, check the second sentence for the real main idea
- For implied main ideas, look for the most frequently repeated concept - that's likely your topic
- Eliminate obviously wrong answer choices first - main ideas are never too specific or too vague
- Practice the 10-word rule: Can you state the main idea in 10 words or less? If not, it might be too detailed
