URM applying 2012-2013 cycle

[bne90]

Thought I'd post to see how I might do in the 2012-2013 cycle so I can better prepare myself when it comes to filling out applications. I think it's pretty obvious where I went to undergrad. Any advice is more than appreciated. I have one year left of undergrad and have yet to take the LSAT. I will be taking a year off as well which is why I won't be applying next cycle. Here are my stats:

URM Female; will be marking AA and NA on applications
Expected LSDAS GPA: 3.05-3.17
University GPA: 3.27 - 3.39
My LSAT practice tests are between 168-173 but I have a while to study. I'm starting to consistently break 172 on them however.
Average softs, although some think volunteering on Native American reservations is rare.

I'm pretty confident that my LSDAS GPA at the very lowest will be a 3.1 and my LSAT a 170 or above. Any suggestions to where I should be aiming to get the best shot for biglaw?

It's premature to talk about chances without a real LSAT score.
