Can anyone make a recommendation on books that have more data sufficiency questions? I need to practice more, and I don't know where to get more questions. I have really horrible at them, and they make up 1/3 of the test questions. Any ideas on getting better at DS questions as well would be most appreciated.
Hello - SoCal30 - I don't know if that any good as an advice. But this forum has at least 500+ DS questions (if you will dig into past posts).
