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.
