  • Their vs. There vs. They're: Possession vs. Place vs. Contraction
  • Affect vs. Effect: Verb (usually) vs. Noun (usually)
  • Who vs. Whom: Subject vs. Object

Analogies

Analogies test your ability to recognize relationships between words. The key is identifying the relationship type first, then finding a matching pair.

Common Relationship Types

Antonym: hot : cold

Part to Whole: page : book

Cause to Effect: rain : flood

Tool to User: stethoscope : doctor

Object to Function: pen : write

Degree/Intensity: warm : hot

Strategy for Solving Analogies

  1. Identify the relationship between the first pair of words
  2. Create a sentence that expresses this relationship
  3. Test each answer choice using the same sentence structure
  4. Eliminate choices that don't fit the relationship
  5. Choose the answer with the closest relationship

Sentence Completion

Key Strategies

  1. Read the entire sentence before looking at choices
  2. Look for context clues and signal words
  3. Identify if the blank needs a positive or negative word
  4. Predict what word should fill the blank
  5. Eliminate obviously wrong answers

Signal Words to Watch

Continuation (same direction):

and, also, furthermore, moreover, similarly, likewise

Contrast (opposite direction):

but, however, although, yet, despite, nevertheless
