How do you improve SAT CR part??

Test Preparation
1

<p>I've been working on Critical Reading for a little or more than 3 weeks.
And my score definitely got improved for more than 100 points.
But I am not getting score higher than 700. I make 10 or less mistakes
for CR part, and the score always stay in between 650~670.
I always find myself stuck in the situation where only two plausible
choices are left, and that makes me lose tons of time. Then, I regret
that I spent too much time on one problem. How do you guys decide
or narrow down to one choice if you think two choices seem right?</p>

<p>also, I studied word smart I and II, and I am studying all the vocabularies
that I encountered in the blue book and Princeton Review book. Will that be
enough? because I always think there's going to be crazy vocabs on the
actual SAT test in October.</p>

<p>Help me guys,</p>
