Not sure about Kaplan, I think it depends on which book/software you use. Mine is from 2009.
However, I've stopped doing Kaplan tests, as they hurt my morale and many verbal questions are formatted different from the OG ones. Princeton questions definitely seem easier than the GMATPrep's.
About RC, thanks guys for your thoughts. Lately I'm trying to attack the questions differently. I realized that the
MGMAT technique simply doesn't work for me (I lose too much time writing detailed notes and in the end I have to come back to the text). However, if I only skim the text then it's worse because I don't have a clue in how to solve most of the questions. So, what I'm trying to do is just taking little notes and paraphrasing each paragraph quickly after reading. I can't use too many minutes to read it because I need always at least a minute for every question.
What's your plan for this last month?
I'm thinking about doing 30 questions every day after work, and 2 or 3 CATs on weekends. In addition, I've taken 3 days off to prepare just before the exam day.
Not sure if it will be enough....
