Hello,
Thanks very much for reading my post.

I am a 32 yr old and work as a Business Systems Analyst/ Web Administrator for a medium size high-tech company in the SF Bay Area. I have been at this company for the last eight years (Aug, 2000 to present)

I have taken the GMAT exam twice already and got the following scores:
Jan, 2005: 560 total (Dont remember the breakup)
Feb, 2007: 680 total (89 Percentile) Quant: 44, Verbal: 39, AWA: 5.0

I completed my undergrad in 2000 (B.S) double majored in Physics and Computer Science (GPA: 3.2)

I am interested in getting an MBA because I would like to make a career change into either Product Management or Marketing Research after completing the degree.

I have already gotten admission and have taken 3 classes towards a part-time MBA degree at a local university in the SF Bay area but now I am thinking that the degree I am working towards is not going to give me a competitive edge in today's market. From what I have heard from others and seen around me, it takes a degree from a reputable full-time program to be able to change careers.

Towards that goal, I have enrolled to take the GMAT again and am hoping to get a better score than 680.

I am interested in the following MBA programs:
1) NYU - Stern (my second choice)
2) CMU - Tepper (my first choice)
3) USC - Marshall
4) UT Austin - McCombs
5) Indiana - Kelley

With my background (and without retaking the GMAT) which universities (from the list above) do I stand a chance of getting into? Are there Top 20 programs that I can get into which offer competitive programs and I have not considered?

Any help is greatly appreciated.

Thanks very much.
