I just took it today and ended up with a v score of 41. And SC was, and is, my weakness.
To work it out, I found that going through the
OG Verbal book and simply reading all of the "answers" helped tremendously!
The "instant feedback" received by reading the problem, doing the analysis, then immediately seeing what the correct answer really helped me to get these down. I felt really good during the test that I actually understanding the grammar issues.
Also, for SC I found the Kaplan 800 book to be very good. The questions are crazy hard, but the explanations are very good. If your're out of drilling questions, I hear the Kaplan quiz bank is good too, hard, but hard is good!
Anyhow, SC is what I struggled with through verbal. I'd take the Prep tests and get 10 SC's wrong and all CR and RC correct. I was pissed! Another option, pick up a copy of a "Gregg" reference and study the rules of grammar. I found that to be helpful as well. Finally... I used a grid to help me out.
I'd write A,B,C,D and E vertically down the board then draw a table. On each SC problem, I'd zoom in on the first grammatical error I could find. Immediately, I would scan the questions and put an X next to those that have the error. Simple strategy, but it helped me a ton!
Another thing... read - a lot! If you can get a copy of McKinsey or some other "high end" publications, read them. You'll get a "fell" for what is right...
Good luck! And thanks for your help on the forums. I'm not an "active" poster, but when I have, you've come to my aid right away! Thanks again - best of luck to you!!!
