02 / MATH
Catch the early answer.
Algebra, quadratics, exponentials, geometry, and statistics. The trap is often what you get one step too soon, before the question is actually answered.

The Project 1600 color system
Yellow, the claim
The evidence the problem actually gives you. Nothing extra, nothing assumed.
Red, the trap
The wrong answer built to feel right because it matches a predictable mistake.
Green, the answer
The correct choice plus the lesson you carry into the next question.
Why it exists
A top SAT score should not depend on expensive tutoring. The test is finite, patterned, and learnable. Project 1600 keeps the bank free so anyone can study how the SAT builds traps and turn that knowledge into points.
