Quant preparation: Sufficient for a good result or not?

Hi there,

I am going to take the GMAT next week and would be glad to hear about your experience with preparing for the quant section.

I have been preparing for the GMAT for about 2 weeks now and one week remains. Since I am not a native english speaker, I put my focus on the quant section in order to receive a high score (and since I am applying for a Master of Finance program, quant is regarded by most of my target universities as the most important part of the GMAT).

Right now, I am through with the about 700 quant questions, I got 560 of them initially right and 140 wrong. About 40 were wrong because I did not focuse on the question properly - so about 100 questions remain wrong because I was unable to identify the concept behind the question. After I am done with correcting my errors I should basically be able to solve all 700 Solving & DS problems from the Red and the Green official GMAT book. What I would like to know is whether you think this is sufficient in order to receive a good math score (good means around 46, 47 up to 51).

If you believe my preparation is not sufficient, what else can you recommend? (Additionally to the GMAT books I am working with the Manhattan Review stuff for preparation.)

Another topic I am interested in is the score itself: What's that about the scores beyond 51? I read several times that it is technically possible to score up to 60 in Quant and Verbal, however, I have never seen a score beyond 51 somewhere. Are these scores only theoretically possible?

Thanks very much for sharing your impressions and experience with the GMAT with me!

Regards

Florian
