Repacking is about clarity: keep variables named, include small sketches, annotate common interpretation rules, and prioritize the handful of formulas that drive most HL exam marks (elasticities, multiplier, cost/revenue relationships, GDP identity). That focused one- or two-page booklet will beat a longer, cluttered list every time.

This is where the concept of a "Repack" comes in. A formula booklet repack isn't just a copy of the official equations; it’s a strategically reorganized toolkit designed for speed, clarity, and application. A typical "repack" organizes formulas by the core

• Formula: $YED = \frac% \Delta Q_d% \Delta Y$ (Where $Y$ = Income)
• The "Repack" Interpretation:

  Repack solution:
  Multiplier = 1 / (MPS + MPT + MPM). MPS = 1 – MPC = 0.25.
  k = 1 / (0.25 + 0.1 + 0.05) = 1 / 0.4 = 2.5.
  ΔGDP = 40M × 2.5 = $100 million.
