summary
the content provides strategies for solving gmat word problems, focusing on backsolving as an effective alternative to algebraic solutions.
  • backsolving involves starting with one of the numerical answers and working backwards to see if it makes sense.
  • a recommended strategy is to begin with answer choice c, which statistically offers a 20% success rate on the first try and allows for quick elimination of other options.
  • an alternative strategy suggests starting with answer choice b, potentially increasing the chances of finding the correct answer on the first guess to 40%.
  • practical application of backsolving is demonstrated through practice questions, showing how to efficiently eliminate incorrect answers and narrow down to the correct one.
  • the process emphasizes the importance of understanding the problem's requirements and using logical deductions to minimize the number of attempts needed.
