I am in a strange situation.
I am 24 and currently a 2L at R 50-70 law school. I am doing well there: 3.4 GPA - top 20% of my class. However, I have decided that I would really like to get into management consulting or I Banking. I have the option to do a dual degree with the school I am currently enrolled in (also R 50-70) which would entail me doing the MBA in 1 year after this semester and then finishing my 3L year there. The perk would that I will have a full or almost full scholarship there.
However, I would love to get into management consulting at a firm like McKinsey, Bain, or Deloitte. So perhaps it would be worth it to finish law school and then cough up the extra 80-100k of debt to go to a top 10 or a top 20 school. I am not sure if it is worth it financially, especially considering I am already going to be around 120k in debt out of law school. Furthermore, I am not even sure as to my chances of getting into any particular school. I am willing to go anywhere for a job, but would prefer to remain in the Southeast. Please help! Thanks

Where I'm thinking of applying:
Top 10, Vanderbilt (they have already waived my tuition fee and promised an interview in the next month), Emory, Duke, Virginia
My stats coming out of law school:
GMAT 730 96%- 44V 98% - 47Q 70%
J.D. from a tier 2 school with a 3.4-5 GPA, top 15-20% - Extracurriculars: National Trial Team, Student Success Leader, VP of law fraternity,
Undergrad at a non-top100 private school (in the top 20 in the south.) Major Biology- GPA 3.4- Extracurriculars- Student government senator
Work Experience: Taught middle school science for 1 year out of college before law school.
