# GMAT Data Sufficiency Questions (Part 1)

Approximately half of the math questions on the GMAT quantitative section are called **data sufficiency questions**. They’re a bizarre type of problem where instead of actually trying to solve the math question, instead you’re evaluating supporting information (called statements) to determine whether or not you *could* answer the question.

The bad news is, the answer choices are bizarre and take some getting used to, and it’s a very different way of thinking about a math problem than you’ve probably ever done before. The good news is, GMAT data sufficiency questions are eminently beatable, and in this GMAT tutorial we’ll teach you everything you need to know in order to do just that. When you’re done with this lesson, you’ll go from being a bit confused by these question types to wishing there were more of them on the GMAT!
