Day 1 of 60 MarathonPhase 1: Foundations & Traps

Percentages & Multipliers + Linear Seating + Main Idea RCs

Master fractional percentage multipliers, 1-variable linear constraints, and central theme RC identification.

Arithmetic Formula & Trap Book (20-Page PDF)

💡 Tip of the Day: When calculating a% of b vs b% of a, remember they are mathematically identical. 16% of 25 = 25% of 16 = 4.
