The main trick to Sentence Correction is spotting the main errors that pop up time and again. So, what you need is a review of those main error types (can be found in any test prep company's GMAT book but NOT in the Official Guide), and then some practice applying what you've learned - you can re-do the questions in the Official Guide focusing now on those common errors.

Hope this helps!

thanks a lot.

Do the scores above predict anything?

I took the test today, was shocked with my result, Quant questions were way difficult than those in OG11, so prepare accordingly. all the best. Take as many test as possible.
I got some four questions from exponents.

Can i ask you the result if you can tell comforatbly?
Seconf how was the level of English?

Well yes, the scores above predict that you'll likely score in that range. Most students tend to do roughly the same (give or take, say, 50 points) on the real exam as on the practice exams.

What is the variation from the Power Prep Scores ???
