Below are the results of the RC passages i attempted from Kaplan 800 . Can somebody give pointers regarding the area's of improvement ?

Passage
RC1 10:45 (Total Time(min)) ..............4(Number of Questions)..........3(c)..........1(w)
RC2 ~14 (Total Time(min))...............4(Number of Questions)..........1(c)..........3(w)
RC3 ~9 (Total Time(min))...............4(Number of Questions)..........2(c)..........2(w)
RC4 ~14 (Total Time(min))...............4(Number of Questions)..........3(c)..........1(w)

Below is my take away. Others please add what needs to be done to improve further .

Speed is a big issue . In any case should not have taken more than 8 min altogether in all of the passage above.
