Combinations and permutations are a fundamental part of DAT Quantitative Reasoning, and understanding when to use each can make a significant difference on test day.
The key distinction is straightforward:
• Use permutations when order matters
• Use combinations when order does not matter
Many DAT questions are designed to test this exact concept. Once you recognize whether order is important, these problems become much more manageable and consistent.
Students often ask which DAT study materials are actually used in real courses. The DAT Destroyer and Math Destroyer are the core books used in Dr. Jim Romano’s DAT preparation classes.
