GRE Prep · Cheat Sheet
| Question Type | What to Do | Common Trap |
| Main Idea | Find the central claim—accurate AND appropriately scoped | Too narrow (detail), too broad (overstatement), or wrong scope |
|---|---|---|
| Inference | Answer must be necessarily true, not just plausible | "Could be true" ≠ "must be true" |
| Function | Why did author include this? How does it serve the argument? | Confusing what something says with why it's there |
| Strengthening/Weakening | Does this support or undermine the author's claim? | Reversing direction |
| SATA (Select All That Apply) | Check all three choices independently; no partial credit | Stopping after finding one correct answer |
| Wrong | Right | |
| Describes one paragraph detail as main idea | Central claim across entire passage | |
| "Always true" (when author said "sometimes") | Appropriately qualified language | |
| Overly specific or overly general | Balanced to passage's actual scope | |
| Signal | Meaning | Blank Direction |
| Although, despite, however, yet, but, while, even though | Contrast | Opposite of adjacent clause |
| Therefore, thus, hence, as a result, consequently, furthermore, moreover | Extension | Same direction as context |
| Because, since, given that, caused by, so | Cause-Effect | Caused by or causes context |
| Trap | Example | |
| Right semantic family, wrong direction | "Abundant" when context demands "scarce" | |
| Right direction, wrong degree | "Slightly upset" when passage demands "outraged" | |
| Ignoring reversal earlier in sentence | Missing a contrast signal that flips meaning | |
| Tone mismatch | Formal word in informal passage or vice versa | |
| Situation | Decision | |
| Inference question + "must be true" vs. "could be true" | Pick "must be" | |
| Main idea + too narrow vs. too broad | Both are wrong; find middle ground | |
| SATA + found one correct answer | Keep checking other two | |
| TC + word "sounds okay" but you haven't predicted | Reread with prediction first | |
| Contrast signal in TC | Blank must oppose adjacent clause | |
| Two-blank TC + one blank is clear | Solve the clear one first | |
| Contrast | Extension | |
| "However," "yet," "but" | "Therefore," "thus," "furthermore" | |
| Blank opposes prior clause | Blank continues/amplifies prior clause | |
| Inference (Must Be True) | Consistency (Could Be True) | |
| Necessarily follows from passage | Compatible with passage | |
| GRE standard | Everyday inference | |
| Main Idea | Primary Purpose | |
| Central claim | Author's goal (persuade, describe, analyze) |
✓ RC: Read for structure & argument, not facts ✓ RC: Pivot sentences = high-priority content ✓ TC: Predict before peeking at choices ✓ TC: Identify logic signals (contrast vs. extension) ✓ Multi-blank: Each answer independent; all must be correct ✓ Inference: "Must be true," not "could be true" ✓ SATA: Evaluate all three independently; no partial credit ✓ Always reread with your answer inserted
