All in all
It seems as though it is not impossible to go into BigLaw, it may be a little unrealistic. But dont let that deter you at all.
I think i heard someone in here say lower your expectations. The Hell???
Never lower your expectations. If you keep them high, you will succeed in law school and get that BIGLAW job because you worked hard and graduated in the top 10% of your class. I just would look more favorably at the person who has the higher ranking/better grades than the person who comes from a T14 with a lower rank and GPA who simply relies n their school name to get them to where they want to be.
