Ok.......I did the 1st Full Powerprep test(without essays) and I got a terrible score of 590(78%ile in Math and 43%ile in verbal).

I did notice that the mistakes in Math were silly, I could do most of the qs correctly after I revisited my mistakes. By the time I got to verbal, my thinking got a bit cloudy and I approached most of the problems very mechanically(that is, not much thought put into them after about finishing the 1st half or so part of the verbal Section). I certainly know I can improve a lot in Math by just paying more attention to details but as for verbal, looks like I need practice in all areas, mostly in RC for which I've not come up with an effective approach.
But, I am very positive that I can reach my goal of 700+ and I'm willing to do whatever it takes!
