Summary
The content provides an in-depth exploration of alternative strategies for solving word problems on the GRE, with a focus on backsolving—a method that leverages the numerical answer choices to work backward and identify the correct answer.
  • Backsolving involves starting with one of the numerical answers and working backwards to see if it makes sense, allowing for the elimination of incorrect answers.
  • A recommended strategy is to begin with answer choice C, as this allows for the elimination of either the two larger or two smaller answers, increasing efficiency.
  • An alternative strategy suggests starting with answer choice B, offering a statistical advantage by potentially righting the first guess or narrowing down the options quickly.
  • Practical application of backsolving is demonstrated through practice questions, showing how to effectively use this strategy to solve complex word problems by eliminating incorrect answers.
  • The content underscores the importance of understanding the underlying logic of backsolving and adapting the strategy based on the specifics of the question and the answer choices provided.
