It may be a little late to apply this strategy before you take the test. But some students find that reading well written newspapers and publications can help them improve their verbal scores.

I totally agree with the above - there is, unfortunately, no quick fix for verbal (or math, for that matter). Really, the only way to get that verbal score up is to improve your English reading and grammar abilities. Spending 30-60 minutes per day simply reading well-written English material (I always suggest the Wall Street Journal) will pay much bigger dividends than poring over CR and RC problems - and it's a lot more interesting and less frustrating.

Bon chance!
