DILR rewards set selection discipline more than raw solving speed.
Section shape
- 5-6 sets, 22 questions; typical mix: arrangement, distribution, games, venn, scheduling, scatter plots.
- One or two sets are deliberately unhinged — the elimination filter.
Selection algorithm
- First 3 minutes: skim all sets, classify easy-medium-volatile; commit to 4 sets.
- Solve classification-friendly sets first; leave story-based multi-constraint sets for the last window.
- Partial attempts count: 2 of 4 questions cracked in a hard set still pays.
Skills stack
- Representation: grids, tables, venn templates; constraint stacking order.
- Game-set templates: rankings with win-loss; distribution with fixed totals.
Revise in 30 seconds
- 22 questions across 5-6 sets.
- Skim 3 minutes, commit to 4 sets.
- Partial set attempts still pay.
- Represent before you compute.
