all i need is a 600. or a little bit over that i'd be happy too.
On Verbal - I'm currently getting the 600-700 questions.
I don't think so. I don't think that book is sufficient to get you past the 500-600 level questions, it's very basic. It depends on what you're looking for.
Also - be careful and don't shoot for a score just to land in the average-land. I did that last time around and I hit the score I was looking for but it was so heavily weighted in verbal that my quant percentile was still too weak to be competitive at the schools I was looking at, so even if you're awesome at verbal - you may need to really work at quant.
I'd probably recommend using the OG Tracker with the official guide, do as many of those problems as you can to find your weaknesses and work specifically on those so you're not wasting time - especially since the test is coming up.
