I've heard that some areas are tested more commonly than others in data sufficiency. Things like "Number Properties." Is this true? If it is, does anyone know why? Thanks!
Sure, some concepts are tested more on DS than others, but those frequencies are pretty the same as the frequencies with which the same concepts are tested on PS questions.
You'll find several DS questions on Geometry, Integer Properties, Stats and Percent. Conversely, DS questions related to Counting and Probability are not as common.
Cheers,
