Data Sufficiency
Decide whether statement 1 alone, statement 2 alone, both together, each alone, or neither gives enough information to answer the question. The goal is not to solve everything fully. It is to judge whether the information is actually sufficient.
Read the prompt first, then judge each statement as information, not as an answer.
A statement is only sufficient if it lets you determine a unique answer to the prompt.
Some statements look helpful but still leave multiple possible values. Those are not sufficient.
About this game
Data Sufficiency focuses on whether you have enough information to determine an answer, not on carrying out every calculation in full.
It is useful for sharpening the judgment behind algebra, ratio, percentage, average, and geometry questions that appear in more advanced assessment formats.
