There are two types of multiple-choice questions in mathematics-problem solving and data adequacy judgment. Both of these problems need knowledge about arithmetic, basic algebra and common geometric concepts.

"Problem solving" aims to test your math skills and ability to understand basic math concepts, as well as your ability to infer and solve math problems. Every "data adequacy judgment" question contains a proposition and two sentences. These two sentences containing more information are marked as

( 1)

and

(2)。 It must be judged whether the data given in the sentence is enough to answer the proposition. "Data sufficiency judgment" measures the ability to analyze mathematical problems, identify relevant information and judge sufficient information needed to solve problems.
