+- **Level 2**: ~30-35% (Intermediate reasoning)  
+- **Level 3**: ~20-25% (Advanced reasoning)
+- **Best for**: Realistic performance evaluation

+- **Distribution**: Random across all levels
+- **Variety**: Maximum question diversity
+- **Best for**: Unbiased sampling

+- **Order**: Questions in dataset order
+- **Consistency**: Same questions each time
+- **Best for**: Reproducible testing
