Only GMAT data sufficiency questions (from the GMAT quantitative section) in this test.

You should take this test to see how ready you are to confront that section of the GMAT. Note that a calculator is not allowed. All of these problems consist of a question and two statements. You have to decide whether the data given in the statements, together with knowledge of general math and everyday facts, are sufficient for answering the question. Think carefully before answering, and kick some butt!
