I am spending a large amount of time in solving data sufficiency questions which is impacting my overall performance in the QUANTS section. Usually I take a large amount of time to solve the questions on number systems such as divisibility and finding out factors and also inequalities.
Can any one suggest me some books/guides/strategy to improve my efficiency and speed while solving the data sufficiency questions?
Thanks in advance
