To become good at both of these requires one key thing; you need to be thinking about the structure of the argument while reading the stimulus. After reading each sentence I make a quick mental note as to what part that particular sentence plays within the argument as a whole. It takes a little time to get used to, but when you become efficient it is rewarding as I get tend to get through most CR questions within a minute to a minute-and-a-half.

thanks for the advice.
any advice on where I can prep myself for these 2 topics...
