Data sufficiency questions account for about 1/3, i.e. 12 to 13, of the questions in the quantitative section.
These questions are about working out what is necessary and sufficient data to be able to answer a question which is very different from the usual problems solving questions you have faced.

You are expected to have completed the fractions, exponents, ratios and percents, geometry and properties of numbers tutorials before starting this tutorial.
