DI is reading speed plus three calculation tricks.
Formats on the paper
- Tables, bar, line, pie, stacked, radar, caselet form; count grids; Venn-based counts.
Speed kit
- Approximate first, compute exactly only if options are close.
- Percentage-of-percentage via multipliers; ratio snapshots instead of absolute values.
- Scan all questions first: two of five usually need only one row of the dataset.
Caselet method
- Convert prose to a table before attempting; assign symbols to unknowns.
Revise in 30 seconds
- Read axes and units first.
- Approximate, then compute.
- Convert caselets to tables.
