Pre-law at Emory has a curriculum that has courses that develop the following skills:
Analytic / Problem Solving Skills
Critical Reading
Writing Skills
Oral Communication / Listening Abilities
General Research Skills
Task Organization / Management Skills
Public Service and Promotion of Justice
You would get all of that and more at Goizueta Business School. The truth is that you can major in anything, take the LSAT, and go to law school. I can’t think of a better training ground for law school than GBS. Your original plan of CS and Business works too, but that would be really tough and could take away from a great amount of electives in the college that might interest you on another level. I do think Emory is a great place for you since you are flexible and so is the school.
