Backsolving



Summary
The content provides strategies for solving GRE word problems, focusing on backsolving as an effective alternative to traditional algebraic solutions.
  • 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 based on whether C is too big or too small.
  • An alternative strategy suggests starting with answer choice B, offering a statistical advantage by potentially right or eliminating incorrect answers more efficiently.
  • Practical application of backsolving is demonstrated through practice questions, showing how to apply the strategy and eliminate incorrect answers to find the correct one.
  • The content underscores the importance of understanding and applying different problem-solving strategies for GRE word problems, enhancing test-takers' efficiency and accuracy.
