Hello people,

I was wondering if anyone has used the english bible - wren and martin.
I was planning on buying one, but I am a bit skeptical whether it will help me improve my GMAT score. Please note, I just want to improve the scores, I don't want to improve my language.

I have Kaplan's Verbal and OG. Are there any good books out there like OG, which tell you why you have gone wrong instead of - A is wrong, B is wrong, C has correct grammar, D,E are wrong. Hence C.
