Thank you resh. I have completed OG for SC and OG PS. I haven't started other sections yet.
I have gone through
MGMAT SC book once, but haven't completed all exercises yet. Also, I am not getting enough motivation to go through OG SC again, and may be I need some more time before I do it again.
I am going through OG verbal review SC questions. When I went through OG SC questions, I just marked answers that I felt were correct. This time, I am marking correct answers, as well as noting down what is incorrect with other ones. It is taking little more time, but the web of wrong answers is not looking as complicated as it was looking earlier.
Also, thanks for your suggestion on using Powerscore bible. It's a good point. I need to determine if I will have enough time to go through it though. I haven't gone through OG CR, OG RC, OG DS yet, so that is my first priority.
