## Common DS Mistakes

Summary

The content provides an in-depth exploration of common mistakes made on GMAT data sufficiency questions, offering insights and strategies to avoid these pitfalls.

- Understanding the direction of logic is crucial; avoid backwards logic where the prompt's truth is assumed to validate the statements.
- Do not automatically assume all numbers are positive integers; consider all numerical possibilities including fractions and negative numbers.
- Be aware of mathematical exceptions, such as the unique properties of certain numbers, which can be pivotal in answering data sufficiency questions correctly.
- Analyze each statement independently without carrying over information from one statement to the next to avoid confusion and incorrect conclusions.
- Learning from mistakes is essential for improvement; always delve into the nature of the mistake to ensure it is not repeated.
