Strategy and Trap Recognition
Five topics of pure test discipline, the layer over every content unit. Answering the question actually asked, units and scale, sign and boundary discipline, grid-in mechanics, and trap recognition across content. The errors here cost nothing mathematically and everything on the score report: right work, wrong report, wrong entry, unchecked trap.
Topics
Reference The six disciplines this unit drills, one line each
Answer the ask, not the algebra
$\text{solve } x \to \text{reread} \to \text{grid the named quantity}$
Convert before computing
$90 \text{ min} = 1.5 \text{ h}; \quad \text{axis labels multiply at the read}$
The four sign posts
$a - (-b) = a + b, \quad (-a)^{2} = a^{2}, \quad \text{distributed minus reaches all, negative divisor flips}$
Boundary reads
$\text{at least } n: x \geq n; \quad \text{strict excludes, } \leq \text{ includes}$
Grid entry
$3\tfrac{1}{2} \to 7/2 \text{ or } 3.5; \quad \text{no symbols; fill repeaters or type the fraction}$
One-second checks
$\text{size, sign, direction, range, units, and the reread of the ask}$
